密码套件解码器
输入一个 TLS 密码套件,可以是 IANA 名称、OpenSSL 或 GnuTLS 名称,或十六进制代码点,将其拆解为密钥交换、身份验证、加密算法、模式和 MAC,并给出通俗的安全评估和 IANA 的官方推荐状态。完全在你的浏览器中针对内置的 IANA 注册表副本运行。
TLS 与传输解码在本地针对内置的 IANA TLS 密码套件注册表副本运行。不会向任何地方发送任何内容。
密钥交换组
TLS 在 supported_groups 扩展中协商实际的密钥协商组,与密码套件分开。由于"先收割,后解密"(harvest now, decrypt later)推动向后量子密钥交换迁移,下面的混合组将经典曲线与 ML-KEM 相结合。

All results are computed locally from the cipher suite you enter. The code points, names, and the IANA "Recommended" and DTLS-OK flags come from a bundled snapshot of the IANA TLS Cipher Suite registry; the structural breakdown (key exchange, authentication, cipher, mode, MAC) and the security read-out are derived in your browser. Nothing is looked up remotely.
