我在 Windows Server 2008 R2 上运行 Wireshark 1.8.6 并尝试解密传入的 HTTPS 通信以调试我看到的问题。

我的 RSA 密钥列表设置正确(我认为),但 Wireshark 出于某种原因不会解密 SSL 流量。过去在调试与其他客户端系统的交换时,我已经让它工作了,所以我想知道这里使用的 TLS 是否是特定的(即我已经读到如果使用 Diffie-Hellman,你无法解密,但我可以'不知道这是否是正在使用的)。

我的 RSA 密钥列表条目如下:

IP Address: 192.168.1.27 (the IP address of the server)
Port: 7447
Protocol: http
Key File: set to my .pem (which I created using openssl from a .pfx containing both the public and private key).
Password: blank because it doesn't seem to need it for a .pem (Wireshark actually throws an error if I enter one).

在我的 Wireshark 跟踪中,我可以看到 Client Hello 和 Server Hello,但应用程序数据没有被解密(右键单击 -> Follow SSL Stream 没有显示任何内容)。

我的 SSL 日志粘贴在下面 - 这里有什么我遗漏的东西会告诉我为什么解密失败?我看到一些这样的条目让我担心,但我不确定如何解释它们:

packet_from_server: is from server - FALSE
decrypt_ssl3_record: using client decoder
decrypt_ssl3_record: no decoder available
dissect_ssl3_handshake iteration 1 type 16 offset 5 length 258 bytes, remaining 267 
ssl_decrypt_pre_master_secret key exchange 0 different from KEX_RSA (16)
dissect_ssl3_handshake can't decrypt pre master secret
  record: offset = 267, reported_length_remaining = 59

ssl_decrypt_pre_master_secret 密钥交换 0 不同于 KEX_RSA (16)

看起来您正在使用 DHE 密码套件(至少不是具有 RSA 密钥交换的密码套件),即使您拥有私钥,它也将提供完美前向保密并防止解密这些数据包。

您可能对以下内容感兴趣:

如果这是为了调试,请尝试关闭 DHE 密码套件。

Server Hello通过查看Wireshark中的数据包,您应该能够看到您正在使用的密码套件。


较新的版本也可以直接使用 pre-master secret(阅读Wireshark wiki SSL 页面的“使用 (Pre)-Master-Secret ”部分)。在某些情况下,这也是您可以从客户端获得的东西。无论哪种方式,要使其正常工作,您都需要从两方之一获取预主密钥。以下是 Wireshark wiki 该部分的几个链接:
