Closes #987

背景

用户反馈希望去掉前置 nginx 代理,由服务器进程内部装载 SSL 证书直接提供 HTTPS / WSS。此前 HTTP 侧 Kestrel 已支持 PFX 直连 HTTPS,但 WssPort / WssCertFilePath 是从未被启动代码读取的死配置,WSS 只能靠外层 TLS 卸载;且证书仅支持 PFX,PEM(Let's Encrypt / nginx 用户)无法直接落地。

实现

  • ServerCertificateLoader(新增):HTTPS / WSS 共用的启动期证书加载器。.pem / .crt(大小写不敏感)走 PEM 证书 + 独立私钥路径(支持加密私钥,按私钥头自动识别),其余扩展名沿用 PFX;PEM 加载后重导出 PFX 再装载,规避 Windows SChannel 无法使用临时私钥的问题;路径 / 私钥缺失、文件不存在、密码错误、证书无私钥一律 fail-fast。
  • WSS 直连:ConfigureWebSocketServer 在 WssPort > 0 时预加载证书并经 ListenOptions.AuthenticationOptions.ServerCertificate 挂到 SuperSocket 监听,与明文 WsPort 并存;证书生命周期由启动器持有、停机释放、启动中断兜底释放。未配置 WssPort 时行为与现状完全一致。
  • 配置:新增 HttpsCertificateKeyPath / WssCertificateKeyPath / WssCertificatePassword(完整单词命名;存量 HttpsCertPath / WssCertFilePath 不改名);WSS 证书配置独立于 HTTPS、不隐式回落;WssCertificatePassword 纳入 AppSetting 脱敏清单。
  • 本地化:新增 StartUp.Certificates.* 六个错误消息键与 SecureListenerConfigured 日志键(中英双语);移除被取代的三个 HttpsCert* 死键。
  • 文档:五语言 README 配置表补齐 WssPort / WssCertFilePath 及新字段行,各新增「无 nginx 直连 HTTPS / WSS」配置说明段。

验收(Opus 复核)

  • ✅ 全仓 dotnet build Server.slnx:0 警告 0 错误;check_keys.py 本地化键一致性通过。
  • ✅ 定向测试 57/57 通过:证书加载矩阵(PFX 有效 / 路径空 / 文件不存在 / 密码错 / PEM 有效含 .pem 与 .crt / PEM 缺私钥 / 私钥密码错 / 无私钥 PFX / 与 HTTPS 配置独立性)+ 真实 wss:// 握手集成测试(自签证书、指纹固定信任、PFX/PEM/加密 PEM 三格式 × 明文端口并存)+ 脱敏与配置测试。
  • 🔧 验收修复一处 Codex 实现缺陷:只赋 ServerCertificate 时 DefaultConnectionStreamInitializersFactory 因 EnabledSslProtocols == None 不装配 SslStreamInitializer,WSS 监听实际是明文(握手超时);已显式设 SslProtocols.Tls12 | TlsProtocols.Tls13 并加注释说明该判定链。
  • 🔧 清理本次重构产生的三个无引用 HttpsCert* 死键(Keys + 双语 resx)。

边界(本期不做)

证书热更新、明文端口关闭开关、TCP / KCP 链路 TLS、发现层广播 wss:// 端点(见 #987 边界节)。

Summary by CodeRabbit

  • 新功能
    • HTTPS 和 WSS 现支持使用 PFX 或 PEM 证书;PEM 可配置独立私钥及密码。
    • 可通过独立端口启用 WSS TLS,且与 HTTPS 证书配置相互独立;明文 WebSocket 仍可使用。
    • 配置序列化时会脱敏 WSS 证书密码。
  • 改进
    • 证书路径、文件、私钥或密码无效时,启动阶段会报告相应错误。
    • 更新了多语言配置文档,补充 HTTPS/WSS 设置与证书要求。

- 新增 ServerCertificateLoader:PFX/PEM 统一加载,.pem/.crt 需独立私钥路径,
  支持加密私钥,加载后重导出 PFX 兼容 Windows SChannel,任何错误启动期 fail-fast
- WebSocket 服务器接通 WssPort:WssPort>0 时经 ListenOptions.AuthenticationOptions
  挂预加载证书;EnabledSslProtocols 必须显式 Tls12/Tls13,否则
  DefaultConnectionStreamInitializersFactory 不会装配 SslStreamInitializer(明文挂起)
- 与明文 WsPort 并存,停机时释放证书;启动中断路径兜底释放
- 新增配置 HttpsCertificateKeyPath / WssCertificateKeyPath / WssCertificatePassword,
  WSS 证书配置独立于 HTTPS 不隐式回落;WssCertificatePassword 纳入脱敏清单
- 新增本地化键 StartUp.Certificates.* 与 SecureListenerConfigured,
  移除被取代的三个 HttpsCert* 死键
- 测试:证书加载矩阵(PFX/PEM/加密 PEM/缺路径/密码错/无私钥)与真实 wss:// 握手
  集成测试(自签证书、指纹固定信任、明文并存、与 HTTPS 配置独立、构建前失败)
- 五语言 README 补齐 WSS/证书配置行并新增「无 nginx 直连 HTTPS/WSS」说明

Merge Risk: Moderate · previous review 4272d

A valid traditional encrypted PEM key can prevent HTTPS or WSS startup despite the configured password. Resolve that compatibility gap before merging, or explicitly narrow the supported format; also preserve the specific error shown when a certificate lacks a private key.

支持传统 OpenSSL 加密 PEM,或明确收窄加密 PEM 契约。

当私钥包含 Proc-Type 和 DEK-Info 头部时,当前代码会调用不带密码的 X509Certificate2.CreateFromPemFile(certificatePath, keyPath)。该 API 不支持这种传统 OpenSSL 加密格式。因此,即使配置了正确的 WssCertificatePassword 或 HttpsCertPassword,有效私钥也可能导致启动失败。

在加载器中增加支持传统 OpenSSL PEM 的解析实现。若项目只支持 RFC 7468 加密 PKCS#8 PEM,则必须同步修改 README、配置注释和启动校验,明确拒绝传统格式,而不能继续使用未限定的“encrypted PEM”描述。

两条审查意见均已处理(e2ebe044):

  1. PrivateKeyMissing 双重包装:HasPrivateKey 校验已移出 try/catch,无私钥时直接抛专属错误(无 InnerException),本地化键恢复可达;测试断言同步收严。
  2. 传统 OpenSSL 加密 PEM:采用「明确拒绝 + 收窄契约」而非实现解析——Proc-Type/DEK-Info 头在加载前识别并抛专属错误(含 openssl pkcs8 -topk8 转换指引),五语言 README 的密码字段与直连说明同步注明「仅限加密 PKCS#8」。理由:.NET 官方仅支持 RFC 7468 加密 PKCS#8,传统格式的 MD5-based KDF 已废弃,现代工具链(certbot / openssl 3.x 默认)产出均为 PKCS#8,一条命令即可转换,不值得为其引入手写解密实现。

验证:全仓构建 0 警告 0 错误、check_keys 通过、定向测试 59/59(含 2 个新增传统格式用例)。
