|
||||||
|
// (注册表 Software\<exehash>\settings\tls_cert,或 yama-ca.pem 文件,见 TlsChannel.cpp
|

|
// 的 InitTls),所有出站 TCP 连接在应用协议首包前先完成 TLS 握手;握手失败一律断开
|
||||||
|
// (fail-closed,不回退明文)。
|
||||||
|
//
|
||||||
|
// 选型:Schannel(Windows 原生 SSPI),零第三方依赖;secur32.lib / crypt32.lib 为
|
||||||
|
// 系统库。单向 TLS:客户端只校验服务端证书链到固定的信任锚,不提供客户端证书,
|
||||||
|
// 客户端身份仍由隧道内登录(V1 PwdHmac / V2 ECDSA)承担。
|
||||||
|
//
|
||||||
|
// 线程模型:Handshake 在连接建立线程上、m_bConnected 置位前调用;Send/Recv 分别在
|
||||||
|
// 发送线程 / 接收线程上调用。上下文生命周期(Handshake/CloseHandles 释放 m_ctx)与
|
||||||
|
// Send/Recv 对 m_ctx 的使用(EncryptMessage/DecryptMessage)由 m_ctxMtx 互斥,避免
|
||||||
|
// 重连线程释放上下文时与使用线程产生 use-after-free。本对象作为 IOCPClient 的值成员
|

|
// 存在,析构时释放上下文。

||||||
|
> 版本:v0.5 · 状态:**Go 服务端 + Windows 客户端已实现并验证;信任锚改存注册表;MFC 主控端(阶段 3)未施工** · 日期:2026-10-14
|
||||||
|
> 目标:让 YAMA 设备端口(TCP 6543)在继续兼容老客户端(明文/XOR)的同时,允许新客户端在拿到证书后按需开启**单向 TLS** 加密传输。
|
||||||
|
> 本期范围:**Go 服务端(`server/go`)+ Windows 客户端**;MFC 服务端(`server/2015Remote`)延后。
|

|
||||||

|

|
||||||
|
|
||||||
|
## 1. 目标与范围
|
||||||
|
|
||||||
|
### 目标
|
||||||
|
|
||||||
|
- 同一 `6543` 端口上,服务端自动区分「明文客户端」与「TLS 客户端」,按连接路由。
|
||||||
|
- 加密是**按部署、按客户端开关**的:证书(注册表值或文件)在 → TLS;证书不在 → 明文(与老客户端一致)。
|
||||||
|
- 老客户端(无证书概念)行为不变、零改动。
|
||||||
|
- 满足 Measure 1 的「传输层真加密 + 抗重放」目标(对 TLS 客户端而言)。
|
||||||
|
|
||||||
|
### 非目标(Non-goals,本次不做)
|
||||||
|
|
||||||
|
- 不做 **mTLS / 客户端证书**:单向 TLS 不验证客户端证书,客户端身份仍由隧道内的现有登录(`PwdHmac` V1 / `ECDSA` V2)承担。
|
||||||
|
- 不做传输层 PSK(`YAMA_TRANSPORT_KEY`)方案——本设计改用证书,更贴合「颁发证书」的运维模型。
|
||||||
|
- 不改应用层协议(flag 帧格式 / XOR / zstd),不做「TLS 内去掉 XOR」的二次精简(后续可选)。
|
||||||
|
- 不做加密开关的运行时热切换(证书只在客户端启动时读取一次,改配置需重启——这正是需求)。
|
||||||
|
- 不做 Linux / macOS / Android 客户端的 TLS 接入(本文以 Windows MFC 客户端为主,其余平台同样式跟进)。
|
||||||
|
- 不做 **MFC 服务端(`server/2015Remote`)的 TLS 接入**——本期只做 Go 服务端(`server/go`),MFC 主控端延后到阶段 3。
|
||||||
|
|
||||||
|
## 2. 现状与复用
|
||||||
|
|
||||||
|
### 2.1 当前传输(已核实)
|
||||||
|
|
||||||
|
服务端 TCP 传输链路:`server/go/server/server.go` `acceptLoop()`(329–360 行)`Accept` 后 `go handleConnection(conn)`;`handleConnection()`(363–425 行)读入 `ctx.InBuffer`,交给 `protocol.Parser`。
|
||||||
|
|
||||||
|
`server/go/protocol/parser.go` `Parse()`(51–85 行):
|
||||||
|
|
||||||
|
1. 可选剥离 HTTP-mask(`POST /...\r\n\r\n` 外壳,`common/mask.h` 的 `HttpMask`);
|
||||||
|
2. `parseHeader()`(88–140 行)调用 `CheckHead()` 识别协议;
|
||||||
|
3. `parsePacket()`(143–225 行)解头 + XOR 解码 + zstd 解压。
|
||||||
|
|
||||||
|
`server/go/protocol/header.go` `CheckHead()`(149–165 行)对前 12 字节依次尝试 8 种头混淆 × 4 种魔数,命中即得 `FlagType`:
|
||||||
|
|
||||||
|
| FlagType | 魔数 | 首字节 |
|
||||||
|
|---|---|---|
|
||||||
|
| FlagHell(4) | `HELL` | `H`=0x48 |
|
||||||
|
| FlagShine(1) | `Shine` | `S`=0x53 |
|
||||||
|
| FlagFuck(2) | `<<FUCK>>` | `<`=0x3C |
|
||||||
|
| FlagHello(3) | `Hello?` | `H`=0x48 |
|
||||||
|
| HTTP-mask | `POST ` | `P`=0x50 |
|
||||||
|
|
||||||
|
> 注意:上表「首字节」是**解密后**的魔数首字节。实际线上,客户端(`common/header.h` 的 `GetHead`)会用 `time() % 12` 随机选一个混淆方法对前 4 字节魔数加密(仅在 `superAdmin` 命中的 `HellEncoder` 路径;默认 `ProtocolEncoder` 直接发明文 `Shine`)。因此**原始首字节可能是任意值**,包括 `0x16`。这正是 TLS 检测不能只看前两字节、必须再加一字节判据的原因(见 §3.1)。
|
||||||
|
|
||||||
|
当前「加密」为 `codec.go` 的 `xorDecoder16`(XOR + 两轮伪随机交换,密钥是明文带内 1~2 字节)+ `header.go` 的 V0~V6 头混淆——**等于明文**。这正是 Measure 1 要解决的。
|
||||||
|
|
||||||
|
### 2.2 客户端登录(已核实,隧道内照常)
|
||||||
|
|
||||||
|
- V1:`client/KernelManager.cpp:1857` 从配置读 `settings/PwdHmac`(预计算摘要),服务端 `auth.go:240` `VerifyMessage(YAMA_PWD, passcode, hmacSig)` 校验。`YAMA_PWD` 只存在服务端,客户端只有摘要,不持有 `YAMA_PWD`。
|
||||||
|
- V2:`auth.go:188` ECDSA P-256 验签(`v2:BASE64`),客户端持私钥、服务端持公钥。
|
||||||
|
|
||||||
|
### 2.3 关键结论(本设计的基础)
|
||||||
|
|
||||||
|
**TLS 作为「透明传输包装」,应用层协议一行不改。** 即:
|
||||||
|
|
||||||
|
```
|
||||||
|
明文客户端: [TCP] = flag 帧 + XOR payload + zstd
|
||||||
|
TLS 客户端: [TCP][TLS] = { flag 帧 + XOR payload + zstd }
|
||||||
|
```
|
||||||
|
|
||||||
|
服务端 `parser.go`/`codec.go`/`header.go`/handler 全部不动;TLS 客户端解密后的字节流就是同一套协议。唯一新增的是**连接建立时的 TLS 检测与解包**。XOR 套在 TLS 里冗余但无害,保留它换来「应用协议零改动、老新客户端共用同一套代码」。
|
||||||
|
|
||||||
|
## 3. 总体方案
|
||||||
|
|
||||||
|
### 3.1 同端口共存 + 首字节检测
|
||||||
|
|
||||||
|
服务端在 `handleConnection` 开头(`Accept` 之后)偷看连接开头 6 字节:
|
||||||
|
|
||||||
|
- 命中 `0x16 0x03 … 0x01`(TLS 握手记录 + TLS 版本号 + 握手类型 ClientHello)→ 交给 `tls.Server` 解包;
|
||||||
|
- 其它 → 走现有明文路径。
|
||||||
|
|
||||||
|
**为何要看第 6 字节**:客户端会随机混淆魔数头(见 §2.1),所以明文连接的前两字节**可能**恰好是 `0x16 0x03`。但混淆只作用于前 4 字节魔数,字节 5 对混淆后的 `HELL` 头恒为 `0x00`,对明文 `Shine`/`POST` 变体是 ASCII 字符——**永远不会是 `0x01`**;而任何 TLS 握手记录里,字节 5 就是握手消息类型,ClientHello 恒为 `0x01`。于是 `0x16 0x03` 加 `b[5]==0x01` 三重判据让误判概率趋近于零。
|
||||||
|
|
||||||
|
```
|
||||||
|
accept
|
||||||
|
├─ 现有 MaxConnections / per-IP 限流(保持,先于 TLS 握手,廉价拒绝 + 抗握手 DoS)
|
||||||
|
├─ peek 3 字节
|
||||||
|
│ ├─ 0x16 0x03 → tls.Server(conn, tlsCfg)(惰性握手,首次 Read 触发)
|
||||||
|
│ └─ 其它 → 明文
|
||||||
|
└─ handleConnection(conn) // 不区分明文/TLS,tls.Conn 实现 net.Conn
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 客户端行为
|
||||||
|
|
||||||
|
客户端启动时检查「证书文件是否存在」:
|
||||||
|
|
||||||
|
- 不在 → 明文(与老客户端完全一致,默认即此);
|
||||||
|
- 在 → 所有出站 TCP 连接(主连接 + screen/terminal/file 子连接)统一走 TLS。
|
||||||
|
|
||||||
|
### 3.3 架构图
|
||||||
|
|
||||||
|
```
|
||||||
|
┌──────────── 被控端(客户端,无证书) ────────────┐
|
||||||
|
│ TCP ── flag+XOR+zstd ─────────────────────────► │ 明文
|
||||||
|
└───────────────────────────────────────────────────┘
|
||||||
|
┌──────────── 被控端(客户端,有证书) ────────────┐
|
||||||
|
│ TCP ── TLS ── { flag+XOR+zstd } ──────────────► │ 加密
|
||||||
|
└───────────────────────────────────────────────────┘
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
┌──────────────────────┐
|
||||||
|
│ 服务端 6543 │
|
||||||
|
│ peek 首字节路由 │
|
||||||
|
│ ├─ 0x16 0x03 → TLS │
|
||||||
|
│ └─ 其它 → 明文 │
|
||||||
|
│ ── 同一套 parser/handler │
|
||||||
|
└──────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
## 4. 证书模型(单向 TLS)
|
||||||
|
|
||||||
|
- 服务端持有一张**服务端证书 + 私钥**(可自签名,或由自建 CA 签发)。
|
||||||
|
- 客户端持有**信任锚证书**(CA 证书,或自签名服务端证书本身)用于在握手时校验服务端。
|
||||||
|
- 「颁发证书给某客户端」= 把信任锚证书投递到该客户端(**注册表值**,见 §6.1/§9.3)。证书是**共享的信任锚**(不是每个客户端一张唯一证书),「颁发」的本质是**决定给哪个客户端开加密**。
|
||||||
|
- 单向 TLS **不认证客户端身份**;客户端身份仍由隧道内的登录(V1 `PwdHmac` / V2 ECDSA)承担。
|
||||||
|
- 信任锚首选存注册表 `Software\<exehash>\settings\tls_cert`(REG_SZ 直接存 PEM 正文);兼容旧方式:`settings.ini` `[settings] tls_cert` 路径,或 exe 同目录 `yama-ca.pem` 文件。
|
||||||
|
|
||||||
|
## 5. 服务端改动
|
||||||
|
|
||||||
|
### 5.1 配置(`server/go/server/server.go` `Config`)
|
||||||
|
|
||||||
|
新增两个字段,均为证书/私钥文件路径;空 = 禁用 TLS(仅明文,向后兼容):
|
||||||
|
|
||||||
|
```go
|
||||||
|
TLSCertFile string // 服务端证书(PEM)
|
||||||
|
TLSKeyFile string // 服务端私钥(PEM)
|
||||||
|
```
|
||||||
|
|
||||||
|
`cmd/main.go` 读取环境变量(沿用现有 `YAMA_*` 命名):
|
||||||
|
|
||||||
|
```go
|
||||||
|
cfg.TLSCertFile = os.Getenv("YAMA_TLS_CERT")
|
||||||
|
cfg.TLSKeyFile = os.Getenv("YAMA_TLS_KEY")
|
||||||
|
```
|
||||||
|
|
||||||
|
仅当两者都非空才构建 `*tls.Config`;否则 `s.tlsCfg == nil`,`acceptLoop` 走纯明文。
|
||||||
|
|
||||||
|
### 5.2 `tls.Config`
|
||||||
|
|
||||||
|
```go
|
||||||
|
tlsCfg := &tls.Config{
|
||||||
|
Certificates: []tls.Certificate{cert},
|
||||||
|
MinVersion: tls.VersionTLS12,
|
||||||
|
// 单向 TLS:不设 ClientAuth / ClientCAs
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5.3 `handleConnection` 检测 + 回放
|
||||||
|
|
||||||
|
标准 peek 回放:`bufio.Reader` 预读 6 字节,封装成 `bufferedConn`(实现 `net.Conn`,`Read` 委托给 `Reader`),判断后把已读字节一并交给目标。嗅探本身设了 `ReadTimeout` 截止,超时/EOF 则退回原始 conn 走明文,由读循环处理:
|
||||||
|
|
||||||
|
```go
|
||||||
|
func (s *Server) wrapTLS(conn net.Conn) net.Conn {
|
||||||
|
br := bufio.NewReader(conn)
|
||||||
|
_ = conn.SetReadDeadline(time.Now().Add(s.config.ReadTimeout)) // 嗅探受超时约束
|
||||||
|
hdr, err := br.Peek(6)
|
||||||
|
_ = conn.SetReadDeadline(time.Time{})
|
||||||
|
if err != nil {
|
||||||
|
return conn // 超时/EOF:走明文,交由读循环处理
|
||||||
|
}
|
||||||
|
bc := &bufferedConn{Conn: conn, r: br}
|
||||||
|
if isTLSClientHello(hdr) { // 0x16 0x03 且 b[5]==0x01
|
||||||
|
return tls.Server(bc, s.tlsCfg) // 握手惰性,首次 Read 触发
|
||||||
|
}
|
||||||
|
return bc
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5.4 握手超时
|
||||||
|
|
||||||
|
`handleConnection` 首次 `conn.Read` 会触发 TLS 握手,而它已按 `ReadTimeout` 设了 `SetReadDeadline`,因此握手天然受 `ReadTimeout` 约束,无需额外机制。per-IP 限流(现有)继续在握手前生效,压制握手 DoS。
|
||||||
|
|
||||||
|
### 5.5 明确不动的部分
|
||||||
|
|
||||||
|
- `parser.go` / `codec.go` / `header.go`:**零改动**。
|
||||||
|
- `handleConnection` / `processData` / handler 栈:**零改动**(`tls.Conn` 满足 `net.Conn`)。
|
||||||
|
|
||||||
|
## 6. 客户端改动
|
||||||
|
|
||||||
|
### 6.1 证书检测
|
||||||
|
|
||||||
|
启动时(连接前)按优先级找信任锚:① 注册表 `Software\<exehash>\settings\tls_cert`(REG_SZ 存 PEM 正文)→ ② `settings.ini` `[settings] tls_cert` 路径 → ③ exe 同目录 `yama-ca.pem`。找到即走 TLS,否则明文。实现:`client/TlsChannel.cpp` 的 `ReadTrustAnchor()` + `TlsEnabled()`(`std::call_once` 惰性加载、线程安全、幂等)。
|
||||||
|
|
||||||
|
### 6.2 TLS 栈选型(已定:Schannel)
|
||||||
|
|
||||||
|
- **已选 Schannel(Windows 原生 SSPI)**:零第三方依赖/零额外 DLL 部署,`secur32.lib`/`crypt32.lib` 均为系统库(`secur32.lib` 已在 `CFFmpegH264Encoder.cpp:38` 链接)。
|
||||||
|
- 信任锚(PEM/DER 正文,来自注册表或文件)经 `CryptStringToBinaryA` 解码 → `CertCreateCertificateContext` → 内存 `HCERTSTORE`;握手后 `CertGetCertificateChain` 把服务端证书链到该信任锚,`dwErrorStatus == 0` 才放行(含时间有效性)。**严格钉扎**:链引擎用 `hExclusiveRoot` 只信任该 store,排除系统根库,否则公共 CA 签发的证书也能通过。**fail-closed**。
|
||||||
|
- 握手凭据:`SCH_CRED_MANUAL_CRED_VALIDATION | SCH_CRED_NO_DEFAULT_CREDS`,`grbitEnabledProtocols = SP_PROT_TLS1_2_CLIENT`(与 Go 端 `MinVersion: TLS 1.2` 对齐)。
|
||||||
|
- 单向 TLS:不提供客户端证书;客户端身份仍由隧道内登录承担。
|
||||||
|
|
||||||
|
### 6.3 连接层封装
|
||||||
|
|
||||||
|
在 socket 建立后、应用协议首包前插入 TLS 握手(`IOCPClient::ConnectServer`,`m_bConnected` 置位前);`ReceiveData`/`SendTo` 改走 `TlsChannel` 会话。所有出站连接(主连接 + 子连接)统一遵循 TLS 开关,因此子连接同样被加密——服务端按连接检测,天然支持。实现:`client/TlsChannel.{h,cpp}`,接入点 `client/IOCPClient.{h,cpp}`。
|
||||||
|
|
||||||
|
### 6.4 关键:无静默降级(fail-closed)
|
||||||
|
|
||||||
|
**证书文件存在但握手失败(证书不匹配 / 中间人)时,客户端必须报错并放弃连接,禁止回退到明文。** 否则攻击者可制造降级。这必须写进实现与测试。
|
||||||
|
|
||||||
|
### 6.5 实现要点:Schannel 流模式 `DecryptMessage` 的缓冲重组
|
||||||
|
|
||||||
|
Schannel 流模式(`ISC_REQ_STREAM`)下,`DecryptMessage` 会把输入的那段 `SECBUFFER_DATA`
|
||||||
|
**重组**为 4 段输出,而不是就地解密到原偏移:
|
||||||
|
|
||||||
|
| 索引 | 类型 | 内容 |
|
||||||
|
|---|---|---|
|
||||||
|
| `bufs[0]` | `SECBUFFER_STREAM_HEADER` | TLS 记录头(5) + 显式 nonce(8) |
|
||||||
|
| `bufs[1]` | `SECBUFFER_DATA` | **明文** |
|
||||||
|
| `bufs[2]` | `SECBUFFER_STREAM_TRAILER` | 认证标签 |
|
||||||
|
| `bufs[3]` | `SECBUFFER_EXTRA` | 下一条记录的剩余密文(如有) |
|
||||||
|
|
||||||
|
因此客户端 `Recv` 必须从 `bufs[1].pvBuffer`/`bufs[1].cbBuffer` 取明文、`EXTRA` 从 `bufs[3]`
|
||||||
|
取。若误用 `bufs[0]`(记录头+nonce)或从原缓冲首字节取数,会把 TLS 记录头 `17 03 03 …`
|
||||||
|
当作明文交给协议解析器(表现为 `Unknown header`)。`Send` 方向相反:`EncryptMessage` 用
|
||||||
|
`STREAM_HEADER/DATA/TRAILER` 三段布局,本就正确。这一处是联调阶段实际踩到的、唯一的方向性
|
||||||
|
不对称 bug,已修复。
|
||||||
|
|
||||||
|
## 7. 兼容矩阵
|
||||||
|
|
||||||
|
| 客户端 | 服务端行为 | 结果 |
|
||||||
|
|---|---|---|
|
||||||
|
| 老客户端(无证书概念) | 明文路径 | 与现状完全一致 |
|
||||||
|
| 新客户端 · 无证书 | 明文路径 | 与老客户端行为一致(默认) |
|
||||||
|
| 新客户端 · 有证书 | TLS 路径 | 全量加密(主 + 子连接) |
|
||||||
|
|
||||||
|
服务端 TLS 未配置(`YAMA_TLS_CERT/KEY` 为空)时,一切与现状一致,TLS 客户端握手自然失败(fail-closed)。
|
||||||
|
|
||||||
|
## 8. 安全考量
|
||||||
|
|
||||||
|
- **TLS 提供**:机密性、完整性、服务端身份(客户端校验)、抗重放(TLS record 序号 + nonce)。即对 TLS 客户端而言,Measure 1(真加密 + 防重放)达成。
|
||||||
|
- **TLS 不提供**(单向):客户端证书身份——仍由隧道内登录承担;对「未颁证客户端」不强制加密(这是本设计刻意保留的兼容性,也是薄弱点:部署安全性取决于最弱客户端)。
|
||||||
|
- **明文前导**:TLS ClientHello 前几字节明文(协议固有),仅暴露「这是 TLS 客户端」,不含业务数据;客户端不设 SNI(连接目标是 IP,无域名)。
|
||||||
|
- **子连接**:客户端统一走 TLS,screen/terminal/file 子连接一并加密;对应 Measure 2 的「源 IP 绑定」降级为纵深防御,不再是唯一防线。
|
||||||
|
- **证书轮换**:重签服务端证书后,需向已颁证客户端重新投递新信任锚(或在证书到期前提前过渡)。自签名建议 `-days 3650`,到期前统一更换。
|
||||||
|
- **协议强度**:`MinVersion` 固定 TLS 1.2+,套件用 Go 默认安全集(`tls.Config` 默认已排除弱套件)。
|
||||||
|
|
||||||
|
## 9. 部署与运维
|
||||||
|
|
||||||
|
### 9.1 生成证书
|
||||||
|
|
||||||
|
自签名(最简,客户端信任锚即 `yama-server.crt`):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
openssl req -x509 -newkey rsa:2048 -nodes \
|
||||||
|
-keyout yama-server.key -out yama-server.crt \
|
||||||
|
-days 3650 -subj "/CN=yama-server"
|
||||||
|
```
|
||||||
|
|
||||||
|
或自建 CA + 签服务端证书(便于轮换,客户端信任锚为 `ca.crt`):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
openssl req -x509 -newkey rsa:2048 -nodes -keyout ca.key -out ca.crt -days 3650 -subj "/CN=yama-ca"
|
||||||
|
openssl req -newkey rsa:2048 -nodes -keyout server.key -out server.csr -subj "/CN=yama-server"
|
||||||
|
openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 3650
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.2 服务端
|
||||||
|
|
||||||
|
```bash
|
||||||
|
YAMA_TLS_CERT=/etc/yama/server.crt \
|
||||||
|
YAMA_TLS_KEY=/etc/yama/server.key \
|
||||||
|
./server_linux_amd64 ...
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.3 客户端「颁发 + 重启」
|
||||||
|
|
||||||
|
首选:把信任锚 PEM 正文写入注册表值 `Software\<exehash>\settings\tls_cert`(REG_SZ),重启客户端:
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
$pem = Get-Content -Raw 'C:\path\yama-ca.pem'
|
||||||
|
New-Item -Path 'HKCU:\Software\<exehash>\settings' -Force | Out-Null
|
||||||
|
Set-ItemProperty -Path 'HKCU:\Software\<exehash>\settings' -Name 'tls_cert' -Value $pem -Type String
|
||||||
|
```
|
||||||
|
|
||||||
|
- `<exehash>` = 客户端 exe 全路径小写后的 FNV 哈希(`common/iniFile.h` 的 `GetRegistryName()`)。
|
||||||
|
- 客户端以服务(SYSTEM)运行时,注册表落在会话用户的 `HKEY_USERS\<SID>`(`GetCurrentUserRegistryKey()`)。
|
||||||
|
- REG_SZ 直接存 PEM 正文(含换行);客户端动态读取,不受 `iniFile::GetStr` 512 字节固定缓冲限制。
|
||||||
|
|
||||||
|
兼容旧方式:把信任锚复制到客户端目录并命名为 `yama-ca.pem`(或经 `settings.ini` `[settings] tls_cert` 指向),重启客户端。
|
||||||
|
|
||||||
|
移除注册表值(或删除文件)并重启即退回明文。**远程下发/撤销信任锚属后续工作,本期仅支持本地写注册表。**
|
||||||
|
|
||||||
|
## 10. 测试计划
|
||||||
|
|
||||||
|
1. **检测单元**:`isTLSClientHello` 对 `0x16 0x03 … 0x01`(TLS 1.2/1.3 ClientHello)/ `POST ` / `Shine` / 混淆 `HELL`(首两字节恰好 `0x16 0x03` 但 `b[5]==0x00`)/ 短于 6 字节 等判定的单测(已实现 `server/go/server/tls_test.go`)。
|
||||||
|
2. **TLS 未配置**:不设 `YAMA_TLS_*` → 纯明文,行为与现状一致。
|
||||||
|
3. **明文回归**:老客户端 + 新客户端(无证书)均走明文,登录/屏幕/终端/文件全链路不回归。
|
||||||
|
4. **TLS 加密**:新客户端(有证书)→ 握手成功,登录/屏幕/终端/文件子连接全部在 TLS 内跑通;抓包确认 payload 不可读。
|
||||||
|
5. **混合并发**:明文与 TLS 客户端同时在线,互不干扰。
|
||||||
|
6. **fail-closed**:客户端有证书但服务端证书不匹配 / 中间人 → 客户端报错断开,**不**回退明文。
|
||||||
|
7. **握手超时 / 限流**:恶意慢握手被 `ReadTimeout` + per-IP 限流压制。
|
||||||
|
|
||||||
|
## 11. 分期与回滚
|
||||||
|
|
||||||
|
- **阶段 1(Go 服务端,本期优先)**:`Config` + `tls.Config` + `acceptLoop` 检测回放;明文路径零改动。可独立上线、独立验证——用 `openssl s_client` 或 Go 测试客户端即可联调 TLS 链路,无需真实客户端配合。
|
||||||
|
- **阶段 2(Windows 客户端)**:证书检测 + TLS 栈 + fail-closed。
|
||||||
|
- **阶段 3(MFC 服务端 `server/2015Remote`,延后)**:与 Go 服务端同款的 TLS 检测 + 解包接入。设计稿见 `docs/TransportTLS_MFCServer_Design.md`。
|
||||||
|
- **回滚**:服务端清空 `YAMA_TLS_CERT/KEY` 即回到纯明文;客户端删除注册表 `tls_cert` 值(或 `yama-ca.pem` 文件)即回明文。
|
||||||
|
|
||||||
|
## 12. 待定问题
|
||||||
|
|
||||||
|
1. ~~客户端 TLS 栈最终选型~~ → **已定 Schannel**(见 §6.2,2026-10-13 落地)。
|
||||||
|
2. ~~信任锚文件固定名(`yama-ca.pem`)是否需可配置~~ → **已改为注册表 `tls_cert` 值优先、文件回退**(见 §6.1/§9.3,2026-10-14)。
|
||||||
|
3. 是否同步把「TLS 内去掉 XOR」列为后续精简项(当前保留 XOR,换取零协议改动)。
|
||||||
|
4. Linux / macOS / Android 客户端的 TLS 接入排期。

## 1. 目标与范围
|
||||||
|
|
||||||
|
### 目标
|
||||||
|
|
||||||
|
- MFC 服务端在同一个 TCP 端口(6543)上,按连接自动区分「明文客户端」与「TLS 客户端」,路由到各自路径。
|
||||||
|
- TLS 客户端解密后的字节流 == 同一套应用协议(flag 帧 + XOR + zstd),**协议解析/解压/解码零改动**。
|
||||||
|
- 老客户端(无 TLS 概念)行为不变、零改动。
|
||||||
|
- 服务端「启用 TLS」是**配置驱动**的:未配证书 → 纯明文;配了证书 → 新旧并存。
|
||||||
|
|
||||||
|
### 非目标(Non-goals,本次不做)
|
||||||
|
|
||||||
|
- 不做 **mTLS / 客户端证书**:单向 TLS,客户端身份仍由隧道内登录(V1 `PwdHmac` / V2 `ECDSA`)承担。
|
||||||
|
- 不做「TLS 内去掉 XOR」的二次精简(与上游设计一致,保留 XOR 换取零协议改动)。
|
||||||
|
- 不做 **UI**:不新增配置对话框、不加「启用加密」复选框、不加证书/私钥路径选择控件。
|
||||||
|
- 不做 **「向在线主机下发启用/撤销加密」指令**:不下发信任锚、不发加密开关指令、不改客户端运行时状态。
|
||||||
|
- 不做 KCP/UDP 传输(`IOCPKCPServer`)的 TLS 接入(本期只做 TCP 设备端口;KCP 另行评估)。
|
||||||
|
|
||||||
|
## 2. 现状与复用(IOCP 数据流 + 四个接缝)
|
||||||
|
|
||||||
|
MFC 服务端 TCP 接收链路:`OnAccept`(`IOCPServer.cpp:1144`)`accept` 后 `AllocateContext`(`:1289`)分配 `CONTEXT_OBJECT`,绑定 IOCP,`PostRecv`(`:1268`)投递首个 `WSARecv`(`:1278`,收进 `wsaInBuf`→`szBuffer[PACKET_LENGTH]`,`:1215`)。收满后 `HandleIO(IORead)`(`:746`)→ `OnClientReceiving`(`:892`)→ `ParseReceivedData`(`:796`)。
|
||||||
|
|
||||||
|
原始 socket 字节在整套流程里各只有**一个入口**和**一个出口**,这是 TLS 能做成「过滤器」而非「改写」的根本原因:
|
||||||
|
|
||||||
|
| 接缝 | 位置 | 作用 |
|
||||||
|
|---|---|---|
|
||||||
|
| ① 收包咽喉点 | `IOCPServer.cpp:805` `InCompressedBuffer.WriteBuffer(szBuffer, dwTrans)` | 原始字节进入协议解析的**唯一**位置(`szBuffer` 全文件仅此一处消费) |
|
||||||
|
| ② 发包咽喉点 | `IOCPServer.cpp:1000` `WSASend(...wsaOutBuffer...)` | `OutCompressedBuffer` 上行的**唯一**位置 |
|
||||||
|
| ③ 嗅探点 | `OnAccept`→`PostRecv`;`OnClientInitializing`(`:790`)现为空桩 `return TRUE` | 首次收到数据处,可挂 ClientHello 判定 |
|
||||||
|
| ④ 状态字段 | `Server.h:332` `CONTEXT_OBJECT`(`szBuffer`/`wsaInBuf`/`InCompressedBuffer`/`InDeCompressedBuffer`/`OutCompressedBuffer`/`Parser` 等,`:359-398`) | 新增 TLS 会话指针 + 标志位 |
|
||||||
|
|
||||||
|
**关键结论(本设计的基础)**:TLS 作为「透明传输包装」,加解密插在 ①② 两处,③ 做新旧分流,④ 加一个 per-connection 状态。`ParseReceivedData` 内的 `Parse`/解压/`Decode`、`WriteContextData` 内的 `Encode`/压缩/掩码,**全部不动**。这与上游 Go 服务端「`tls.Conn` 满足 `net.Conn`、parser 零改动」是同一策略(见上游 §2.3)。
|
||||||
|
|
||||||
|
## 3. 总体方案
|
||||||
|
|
||||||
|
### 3.1 按连接嗅探(与 Go 服务端同款判定)
|
||||||
|
|
||||||
|
首次收到数据后,只看 `szBuffer` 前 6 字节:
|
||||||
|
|
||||||
|
- 命中 `0x16 0x03 … 0x01`(TLS 握手记录 + TLS 版本号 + ClientHello)→ TLS 路径;
|
||||||
|
- 其它 → 明文路径(老客户端透明,一行不改)。
|
||||||
|
|
||||||
|
判据与 Go 端 `isTLSClientHello`(`0x16 0x03` 且 `b[5]==0x01`)**完全一致**,理由也一致:客户端会随机混淆魔数头(见上游 §2.1),明文前两字节可能恰为 `0x16 0x03`,但字节 5 对混淆头恒非 `0x01`,故三重判据误判率趋近于零。
|
||||||
|
|
||||||
|
### 3.2 数据路径 = 条件过滤器
|
||||||
|
|
||||||
|
```
|
||||||
|
OnAccept → PostRecv
|
||||||
|
│
|
||||||
|
首次 IORead 完成(嗅探 szBuffer[0..5])
|
||||||
|
┌─────┴─────┐
|
||||||
|
明文(其它) TLS(0x16 0x03 .. 0x01)
|
||||||
|
│ │
|
||||||
|
ParseReceivedData TLS 握手(AcceptSecurityContext)
|
||||||
|
(现状,零改动) │ 成功
|
||||||
|
│ ▼
|
||||||
|
│ 握手后:IORead → DecryptMessage → 明文 → InCompressedBuffer.WriteBuffer
|
||||||
|
│ 发送:OutCompressedBuffer → EncryptMessage → WSASend
|
||||||
|
└────────── 同一套 Parse/Encode/解压/压缩 ──────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
明文连接与握手后的 TLS 连接,下游共用同一套 `Parse`/`Encode`/解压/压缩。唯一差别是 ①② 两处各多一个 `if (tls) 加解密 else 直通` 分支。
|
||||||
|
|
||||||
|
## 4. 配置设计(含未来 UI/指令的预埋)
|
||||||
|
|
||||||
|
### 4.1 配置面(本次定键名,UI 后期加)
|
||||||
|
|
||||||
|
MFC 服务端配置走 `THIS_CFG`(`config`/`iniFile`,`GetInt`/`GetStr(section,key,default)`,见 `2015Remote.cpp:481-543` 用法)。新增 `[tls]` 节,三键(**已拍板 PEM + CNG**,见 §5.6、§12):
|
||||||
|
|
||||||
|
```ini
|
||||||
|
[tls]
|
||||||
|
Enabled = 0 ; 是否启用传输层加密(0/1)
|
||||||
|
CertPath = "" ; 服务端证书路径(PEM,-----BEGIN CERTIFICATE-----)
|
||||||
|
KeyPath = "" ; 服务端私钥路径(PEM PKCS#8,-----BEGIN PRIVATE KEY-----)
|
||||||
|
```
|
||||||
|
|
||||||
|
三键都是**短字符串路径**,不落 PEM 正文,故不受 `iniFile::GetStr` 512 字节固定缓冲限制(该限制只在「存 PEM 正文」时才成问题,客户端已为此单独绕行,见上游 §6.1)。
|
||||||
|
|
||||||
|
### 4.2 未来不返工的四条硬约束(本次预埋)
|
||||||
|
|
||||||
|
1. **配置单一访问器**:TLS 开关与身份路径只经一个中心对象 `ServerTlsIdentity` 暴露:`Load(config&)` / `IsEnabled()` / `IsReady()` / `IsLoadError()` / `Cred()`。未来 UI 改配置、指令查询「我当前是否加密态」都走这同一个入口,禁止代码里散落 `GetInt("Enabled")`。
|
||||||
|
2. **身份加载做成可重入,绝不用 `std::call_once`**:`ServerTlsIdentity::Load(config&)` 每次调用重新加载证书+私钥并重建凭据句柄。本次启动时调一次;未来「轮换证书 / 开关切换」可再调。这是对客户端 `TlsEnabled()` 用 `std::call_once` 一次读死、不可热切换(见上游 §6.1 与 `docs/tls-cert-push-revoke-deferred` 相关记忆)的**主动规避**。
|
||||||
|
3. **「我是否 TLS 就绪」是全局只读态,与每条连接的 TLS 态分开**:`ServerTlsIdentity::IsEnabled()`(全局配置态)/ `IsReady()`(身份加载成功)与 per-connection 的「该连接是否走 TLS/握手是否完成」是两个概念。未来指令/UI 只碰前者。
|
||||||
|
4. **按连接嗅探本身就是为混合上线准备的**:服务端开 TLS 后,没切换的旧主机照样明文连、已切换的走 TLS。未来「下发开启指令」只改客户端行为,服务端传输层不用动。
|
||||||
|
|
||||||
|
## 5. 服务端改动详述
|
||||||
|
|
||||||
|
### 5.1 `CONTEXT_OBJECT` 字段(`Server.h`,加 4 项)
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// 每连接传输层状态(单向 TLS,见 §5.2);跨线程(握手线程写 TLS_Ready,工作线程读)用 atomic 保序
|
||||||
|
enum ServerTlsState {
|
||||||
|
TLS_Unclassified = 0, // 尚未收到足够字节判定(缓冲 tlsPreClassify)
|
||||||
|
TLS_Plain = 1, // 明文客户端,直通现有解析路径
|
||||||
|
TLS_Handshaking = 2, // TLS 客户端,握手线程阻塞 AcceptSecurityContext 中
|
||||||
|
TLS_Ready = 3, // TLS 握手完成,收包解密 / 发包加密
|
||||||
|
};
|
||||||
|
ServerTlsSession* tls = nullptr; // 懒分配;握手完成后承载加解密状态
|
||||||
|
std::atomic<int> tlsState{ TLS_Unclassified }; // ServerTlsState
|
||||||
|
std::vector<BYTE> tlsPreClassify; // 分类前缓冲的首批字节(嗅探 ClientHello 头)
|
||||||
|
bool bSendPending = false; // 发送在途抑制(见 §5.5);受 SendLock 保护
|
||||||
|
|
||||||
|
void FreeTls(); // delete tls; tls = NULL;(定义在 ServerTlsSession.cpp,避免本头拖入 Schannel)
|
||||||
|
```
|
||||||
|
|
||||||
|
生命周期见 §5.7:`InitMember` 时复位 `tlsState`/`tlsPreClassify`/`tls`,析构 / 回收时 `FreeTls()`。
|
||||||
|
|
||||||
|
### 5.2 嗅探与预分类缓冲
|
||||||
|
|
||||||
|
首次 `IORead` 完成时(`OnClientReceiving` 开头,`ParseReceivedData` 之前)判定:
|
||||||
|
|
||||||
|
- `dwTrans >= 6`:看 `szBuffer[0..5]`,一次定死明文/TLS;
|
||||||
|
- `dwTrans < 6`(TCP 把 ClientHello 头分片,极罕见但须正确):把这 `dwTrans` 字节追加进 `tlsPreClassify`,`PostRecv` 继续收,直到攒够 6 字节再判定。判定后清空 `tlsPreClassify`。
|
||||||
|
|
||||||
|
明文连接判定后,把 `tlsPreClassify`(如有)+ 本次 `szBuffer` 一并按现状喂给 `ParseReceivedData`,保证分片字节不丢。
|
||||||
|
|
||||||
|
### 5.3 握手(已拍板方案 A)
|
||||||
|
|
||||||
|
服务端握手需 `AcceptSecurityContext`(Schannel 入站),与客户端 `InitializeSecurityContext`(出站)**不通用**,需新写。数据阶段的 `DecryptMessage`/`EncryptMessage` 是同步缓冲变换,与异步收发包天然兼容,两个方案都复用。
|
||||||
|
|
||||||
|
**方案 A:专用握手线程(阻塞式,已实施)**
|
||||||
|
- 首次 `IORead` 判定为 TLS 后,此刻 `WSARecv` 已因完成回调结束、socket 上**无 pending overlapped 操作**,可安全转交一个短命线程做阻塞握手。
|
||||||
|
- 线程内用**与客户端 `TlsChannel::Handshake` 同型的阻塞 Schannel 循环**跑 `AcceptSecurityContext`(`TlsChannel.cpp` 已证明该模式可靠),把已收到的 ClientHello 字节(`tlsPreClassify`,可能是分片)作为初始输入,后续 handshake 航程走阻塞 `recv`/`send`;握手前把 socket 切回阻塞态并设 15s 收发超时。
|
||||||
|
- 成功 → `tlsState.store(TLS_Ready)`,`PostRecv` 投递首个 `IORead`,回到 IOCP 正常流程;失败 → 关连接(fail-closed,§8)。
|
||||||
|
- 优点:复用客户端已验证的阻塞 Schannel 代码形态、状态最少;缺点:每个 TLS 连接多一个短命线程(仅在握手期间存活)。
|
||||||
|
|
||||||
|
**方案 B:异步状态机(无额外线程,更贴合 IOCP)**
|
||||||
|
- 握手由 `IORead`/`IOWrite` 完成回调推进:每次回调喂一段握手字节给 `AcceptSecurityContext`,按其返回(`SEC_I_CONTINUE_NEEDED` → 继续收/发;`SEC_E_OK` → 完成)驱动下一动作。
|
||||||
|
- 优点:无额外线程、与现有 IOCP 事件循环同构;缺点:状态管理明显更重,需把「握手待收/待发/完成」编码进 per-connection 状态。
|
||||||
|
|
||||||
|
**已拍板(2026-10-14)**:采用 **方案 A**(简单、复用客户端阻塞 Schannel 经验、风险低)。方案 B 留作后续压测发现短命线程开销不可接受时再演进;二者切换只影响 §5.3,不影响 ①②④ 的过滤器设计。
|
||||||
|
|
||||||
|
### 5.4 收包解密(接缝 ①,`ParseReceivedData` 之上)
|
||||||
|
|
||||||
|
`OnClientReceiving` 里,明文与 TLS 分叉:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
int st = ContextObject->tlsState.load(std::memory_order_acquire);
|
||||||
|
if (st == TLS_Ready) {
|
||||||
|
// 1) 把 szBuffer[0..dwTrans] 喂给 DecryptMessage,得到明文 plain、长度 n
|
||||||
|
// 2) 处理 SECBUFFER_EXTRA:多余密文留存到 tls 对象内部缓冲(m_raw),下次续解(见上游 §6.5)
|
||||||
|
// 3) plain 为空(记录分片未齐)→ PostRecv 继续收;否则 ContextObject->InCompressedBuffer.WriteBuffer(plain.data(), n);
|
||||||
|
} else {
|
||||||
|
ContextObject->InCompressedBuffer.WriteBuffer(szBuffer, dwTrans); // 现状,零改动
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
即 ① 从「一行直写」变成「条件分支」,明文侧原文不动。解密缓冲重组(`STREAM_HEADER/DATA/TRAILER/EXTRA` 四段布局)已在上游 §6.5 踩过坑、给出正确写法,服务端直接沿用(`ServerTlsSession::Decrypt` 内维护 `m_raw` 续解缓冲)。
|
||||||
|
|
||||||
|
### 5.5 发包加密(接缝 ②,`OnClientPreSending` 之上)
|
||||||
|
|
||||||
|
`OutCompressedBuffer` 是「可能残留上一轮未发完密文」的可变缓冲:异步 `WSASend` 在途时,新明文由 `WriteContextData` 追加在尾部。因此 `OnClientPreSending`(`IOCPServer.cpp`)**只加密本次新追加的尾部明文**,而非整个缓冲:
|
||||||
|
|
||||||
|
1. 追加前记 `oldLen = OutCompressedBuffer.GetBufferLength()`;
|
||||||
|
2. `WriteContextData` 追加新明文后,`plainLen = totalLen - oldLen`,只对 `GetBuffer(oldLen)` 起的 `plainLen` 字节调用 `tls->Encrypt` 得密文 `wire`;
|
||||||
|
3. `TruncateBuffer(oldLen)` 回退尾部明文(**不用 `ClearBuffer`**:后者会 `DeAllocateBuffer`,可能 `VirtualFree` 正在被在途 `WSASend` 引用的底层内存),再 `WriteBuffer(wire)` 追加新密文。
|
||||||
|
|
||||||
|
这样 `OutCompressedBuffer` 始终保持一串合法 TLS 记录。若把整个缓冲重新加密,会把旧密文二次加密,客户端解密后得到「旧 TLS 记录」→ `Unknown header 17 03 03`。
|
||||||
|
|
||||||
|
**发送唤醒的并发抑制(`bSendPending`)**:`OnClientPreSending` 每次 `Send2Client` 若都 `PostQueuedCompletionStatus(IOWrite, 0)`,则每个 `OnClientPostSending(ctx, 0)` 都会对整个缓冲再发起一次 `WSASend`;背靠背小包(终端 `resize → COMMAND_NEXT → resize`)会触发多个并发 `WSASend` 读到同一段可变内存,产出重复/错位密文(客户端 `DecryptMessage` 失败,`WSAGetLastError()` 残留 `6001 = ERROR_DECRYPTION_FAILED`)。故新增 `bool bSendPending`(受 `SendLock` 保护):仅在 `!bSendPending` 时投递 IOWrite 并置位;`OnClientPostSending` 在缓冲排空(最后一个 `WSASend` 完成)或发送失败时清零;`InitMember` 复用对象池时复位。在途 `WSASend` 的完成回调会看到排空后仍残留的新数据并继续发送,无需再投递。后续 `OnClientPostSending` 的部分发送循环照旧——它发送的已是密文字节,逐段 `WSASend` 天然成立。
|
||||||
|
|
||||||
|
### 5.6 证书/私钥加载(Schannel 入站凭据,已拍板 PEM+CNG)
|
||||||
|
|
||||||
|
`AcquireCredentialsHandle` 取 `SCHANNEL_CRED`(入站)时需一个**已绑定私钥的证书**。已拍板用 **PEM + CNG**(与 Go 端 `YAMA_TLS_CERT/KEY` 同构,服务端与 Go 共用同一对密钥):
|
||||||
|
|
||||||
|
- **证书**:`CryptStringToBinaryA(CRYPT_STRING_ANY)` 把 PEM 解为 DER → `CertCreateCertificateContext(X509_ASN_ENCODING)`。
|
||||||
|
- **私钥(仅 PKCS#8)**:Schannel 入站凭据要求私钥是**「能按名重开」的持久化键**——`NCryptImportKey` 产出的是匿名临时键,绑定 `CERT_NCRYPT_KEY_HANDLE_PROP_ID` 后 Schannel 仍拿不到(`AcquireCredentialsHandle` 返回 `SEC_E_NO_CREDENTIALS` `0x8009030e`)。因此:
|
||||||
|
1. **导入临时键并导出裸 BLOB**:`NCryptOpenStorageProvider(MS_KEY_STORAGE_PROVIDER)` + `NCryptImportKey(NCRYPT_PKCS8_PRIVATE_KEY_BLOB)` 得临时键(`hProvider` 不能传 NULL——默认提供者解析实测返回 `NTE_INVALID_HANDLE` `0x80090026`,须显式打开 KSP);再 `NCryptSetProperty(NCRYPT_EXPORT_POLICY_PROPERTY=ALLOW_PLAINTEXT_EXPORT|ALLOW_EXPORT)` 后 `NCryptExportKey(BCRYPT_RSAFULLPRIVATE_BLOB)` 得裸 RSA 私钥 BLOB。
|
||||||
|
2. **写入持久化键**:`NCryptCreatePersistedKey(BCRYPT_RSA_ALGORITHM, "YamaServerTlsKey", AT_KEYEXCHANGE, NCRYPT_OVERWRITE_KEY_FLAG)` → `NCryptSetProperty(BCRYPT_RSAFULLPRIVATE_BLOB)` → `NCryptFinalizeKey`。`NCryptSetProperty` 只认裸 BLOB、不认 PKCS#8(直接设 `NCRYPT_PKCS8_PRIVATE_KEY_BLOB` 实测 `NTE_NOT_SUPPORTED` `0x80090029`)。
|
||||||
|
3. **按名绑定**:`CertSetCertificateContextProperty(CERT_KEY_PROV_INFO_PROP_ID, CRYPT_KEY_PROV_INFO{ pwszContainerName="YamaServerTlsKey", pwszProvName=MS_KEY_STORAGE_PROVIDER, dwProvType=0, dwKeySpec=AT_KEYEXCHANGE })`。Schannel 经 `CryptAcquireCertificatePrivateKey` 按名在 KSP 里重开该键。
|
||||||
|
- **入站凭据**:`AcquireCredentialsHandleA("Microsoft Unified Security Protocol Provider", SECPKG_CRED_INBOUND, &SCHANNEL_CRED{ cCreds=1, paCred=&cert, grbitEnabledProtocols=SP_PROT_TLS1_2_SERVER, dwFlags=NO_DEFAULT_CREDS })`。
|
||||||
|
|
||||||
|
关键点:**私钥必须是 PKCS#8**(`-----BEGIN PRIVATE KEY-----`);若拿到的是 PKCS#1(`-----BEGIN RSA/EC PRIVATE KEY-----`),用
|
||||||
|
`openssl pkcs8 -topk8 -nocrypt -in server.key -out server.key` 转换。证书上下文生命周期交给进程级 `g_cert`,持久化键句柄交给 `g_persistedKey`;`FreeIdentity` 里按序 `FreeCredentialsHandle` → `CertFreeCertificateContext` → `NCryptDeleteKey`(`NCryptDeleteKey` 会同时释放句柄,勿再 `NCryptFreeObject`)。
|
||||||
|
|
||||||
|
### 5.7 生命周期(context 池化复用)
|
||||||
|
|
||||||
|
`CONTEXT_OBJECT` 经 `AllocateContext`(`:1311`)从 `m_ContextFreePoolList` **复用**、`InitMember`(`:1314`)复位。故 TLS 状态必须在 `InitMember` 里清空 `tlsPreClassify`、`FreeTls()`、复位 `tlsState`(`store(TLS_Unclassified)`)与 `bSendPending=false`(避免上次连接残留的在途标志抑制新连接发送),并在 `~CONTEXT_OBJECT`(`Server.h:346`)`FreeTls()`。否则「前一个 TLS 连接的状态漏给下一个明文连接」会直接导致解析错乱。这是唯一需要跨过 `InitMember`/析构两处做的生命周期接线。
|
||||||
|
|
||||||
|
### 5.8 明确不动的部分
|
||||||
|
|
||||||
|
- `ParseReceivedData` 内的 `Parse`/解压/`Decode`、`WriteContextData` 内的 `Encode`/压缩/掩码:**零改动**。
|
||||||
|
- `HeaderParser` / `context`(`context.h`)协议层:**零改动**。
|
||||||
|
- `OnAccept` / `PostRecv` / `AllocateContext` / `RemoveStaleContext` 主结构:**零改动**(仅新增 TLS 分支与字段复位)。
|
||||||
|
- KCP / UDP 传输(`IOCPKCPServer`):**零改动**(不在本期范围)。
|
||||||
|
|
||||||
|
## 6. 新老客户端兼容矩阵
|
||||||
|
|
||||||
|
| 客户端 | 服务端 TLS 状态 | 服务端行为 | 结果 |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 老客户端(无 TLS 概念) | 未配置 | 明文路径 | 与现状完全一致 |
|
||||||
|
| 老客户端 | 已配置 | 嗅探判为明文 → 明文路径 | 与现状完全一致(透明) |
|
||||||
|
| 新客户端 · 无证书 | 未配置 / 已配置 | 明文路径 | 与老客户端一致(默认) |
|
||||||
|
| 新客户端 · 有证书 | 已配置 | 嗅探判为 TLS → 握手 → 加密 | 全量加密 |
|
||||||
|
| 新客户端 · 有证书 | 未配置 | 嗅探判为 TLS → 无证书可握手 → **关连接(fail-closed)** | 拒绝(见 §8) |
|
||||||
|
|
||||||
|
## 7. 与未来「下发/撤销指令 + UI」的接缝
|
||||||
|
|
||||||
|
本次不实现 UI 与指令,但通过 §4.2 四条约束预留干净接缝。二者未来的分工与依赖:
|
||||||
|
|
||||||
|
- **UI**:在 MFC 配置对话框(类 MCP)里加「启用传输加密 + 指定一对密钥」,写入 `[tls]` 三键 → 调 `ServerTlsIdentity::Load(config&)` 重载 → `IsEnabled()` 即时生效。**只碰 §4.2 第 1/2 点,不碰传输层。**
|
||||||
|
- **「向在线主机下发启用/撤销加密」指令**:服务端侧是一条新的命令通道(遍历在线连接广播),客户端侧是**运行时热切换**——收到指令后热加载/删除信任锚、断开重连走新通道。
|
||||||
|
|
||||||
|
**必须先说破的跨端依赖**:这条指令真正的大头在**客户端**——客户端目前读 `tls_cert` 是进程启动读一次、`std::call_once`、**不可热切换**(见上游 §6.1 及 `docs/tls-cert-push-revoke-deferred` 记忆)。因此「下发/撤销」落地时,客户端要先把 `TlsEnabled()` 的一次读死改成「指令驱动的热重载」。**这与本次服务端传输层正交**——只要 §4.2 第 2/3 点把服务端状态做成可重载、可中心化查询,未来就能干净接上,无需回头改本次代码。
|
||||||
|
|
||||||
|
## 8. 安全考量
|
||||||
|
|
||||||
|
- **TLS 提供**:机密性、完整性、服务端身份(客户端校验)、抗重放(TLS record 序号 + nonce)。对 TLS 客户端而言,Measure 1(真加密 + 防重放)达成,与 Go 端一致。
|
||||||
|
- **TLS 不提供**(单向):客户端身份——仍由隧道内登录承担。
|
||||||
|
- **服务端 fail-closed**:服务端收到 TLS ClientHello 但自身未配证书/身份加载失败 → **直接关连接**,禁止把 TLS 字节当协议去解析(否则新客户端握手失败重试 + 服务端狂报解析错)。与客户端 fail-closed 语义对称(见上游 §6.4)。
|
||||||
|
- **握手 DoS**:TLS 握手有 CPU 开销,须受 per-IP 限流(现有)保护;方案 A 的短命握手线程还须加握手超时(`SSPI` 握手期间设 socket 收发超时,超时关连接)。
|
||||||
|
- **部署顺序**(关键):**MFC 服务端证书必须与客户端 CA 一起(或先于)上线**。否则「新客户端(已钉 CA)连旧 MFC 服务端(无证书)」→ 客户端 fail-closed 直接拒绝,表现为「升级客户端后连不上老服务端」。这是设计使然,部署/文档须写明。
|
||||||
|
- **私钥安全**:服务器私钥只在握手时由 Schannel 内部签名使用(ECDHE)或解密预主密钥(RSA),不参与业务数据加解密;私钥文件应最小权限存放、不落日志。真正的长期秘密(CA 私钥)平时离线,仅在签发/轮换服务器证书时使用。
|
||||||
|
|
||||||
|
## 9. 部署与运维
|
||||||
|
|
||||||
|
生成服务端身份(与 Go 端 §9.1 的 `server.crt` + `server.key` 完全同一对密钥;私钥须 PKCS#8):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 若私钥是 PKCS#1(-----BEGIN RSA/EC PRIVATE KEY-----),先转 PKCS#8:
|
||||||
|
openssl pkcs8 -topk8 -nocrypt -in server.key -out server.key
|
||||||
|
```
|
||||||
|
|
||||||
|
MFC 服务端配置(直接指向与 Go 端相同的 PEM 文件):
|
||||||
|
|
||||||
|
```ini
|
||||||
|
[tls]
|
||||||
|
Enabled = 1
|
||||||
|
CertPath = C:\YAMA\server.crt
|
||||||
|
KeyPath = C:\YAMA\server.key
|
||||||
|
```
|
||||||
|
|
||||||
|
重启 MFC 服务端即生效(本次仅启动时读一次,热切换待未来 UI)。删除 `[tls]` 节或置 `Enabled=0` 即回纯明文。
|
||||||
|
|
||||||
|
## 10. 测试计划
|
||||||
|
|
||||||
|
1. **嗅探单元**:`0x16 0x03 .. 0x01`(TLS 1.2/1.3 ClientHello)/ 明文首包 / 混淆头(首两字节 `0x16 0x03` 但 `b[5]!=0x01`)/ 首包 <6 字节分片 的判定。
|
||||||
|
2. **TLS 未配置**:`Enabled=0` 或无证书 → 纯明文,行为与现状一致(老 + 新无证书客户端回归)。
|
||||||
|
3. **明文回归**:老客户端全链路(登录/屏幕/终端/文件)不回归。
|
||||||
|
4. **TLS 加密**:新客户端(有证书)连 MFC 服务端 → 握手成功,登录/屏幕/终端/文件子连接全部在 TLS 内跑通;抓包确认 payload 不可读。
|
||||||
|
5. **混合并发**:明文与 TLS 客户端同时在线,互不干扰(对应未来过渡期)。
|
||||||
|
6. **fail-closed 双向**:① 服务端未配证书但收到 ClientHello → 关连接不误解析;② 客户端有证书但服务端证书不匹配 → 客户端断开不回退明文。
|
||||||
|
7. **握手超时 / 限流**:恶意慢握手被超时 + per-IP 限流压制。
|
||||||
|
8. **连接复用**:一条 TLS 连接断开后,context 回池再被明文连接复用,TLS 状态已复位、无泄漏(§5.7)。
|
||||||
|
|
||||||
|
## 11. 分期与回滚
|
||||||
|
|
||||||
|
- **本期(MFC 服务端传输加密,已实施)**:`ServerTlsIdentity`(PEM+CNG 加载)+ `CONTEXT_OBJECT` 字段(`tlsState` 枚举)+ 嗅探/预分类 + 握手(方案 A)+ ①收包解密 + ②发包加密 + 生命周期复位。可独立验证——用 `openssl s_client` 或复用 Go 端测试客户端联调,无需真实客户端配合。
|
||||||
|
- **后续 A(UI)**:MCP 式配置对话框 + 重载 `ServerTlsIdentity`。
|
||||||
|
- **后续 B(下发/撤销指令)**:服务端指令通道 + **客户端热切换**(客户端 `TlsEnabled()` 改指令驱动,见 §7)。
|
||||||
|
- **回滚**:服务端 `[tls] Enabled=0` 即回纯明文,无需改客户端(客户端无证书时本就明文)。
|
||||||
|
|
||||||
|
## 12. 已拍板决策与仍待定问题
|
||||||
|
|
||||||
|
**已拍板(2026-10-14)**:
|
||||||
|
|
||||||
|
1. **握手方案**:采用 **方案 A(专用阻塞线程)**,见 §5.3。
|
||||||
|
2. **身份文件格式**:采用 **PEM + CNG(`CertPath` + `KeyPath`,私钥 PKCS#8)**,与 Go 服务端共用同一对密钥,见 §5.6。
|
||||||
|
3. **配置节名**:新建 **`[tls]` 节**,键 `Enabled` / `CertPath` / `KeyPath`,见 §4.1。
|
||||||
|
|
||||||
|
**仍待定**:
|
||||||
|
|
||||||
|
1. **KCP/UDP 传输是否也要 TLS**:本期不含,另行评估。
|
||||||
|
2. **MFC 的 MCP 式配置 UI**:显式排除,见 §7;落地时只碰 §4.2 第 1/2 点。
