Hi, I am trying to decrypt SSL/TLS traffic encrypted with a pre-shared key. The cipher I use is PSK-AES128-CBC-SHA. I use the built-in openssl server (sserver) and client (sclient) and it works well but traffic decryption does not work.I've already specified a ssldebug file in wireshark and set the pre-shared key to the same I pass as an openssl argument.

The primary goal of the Transport Layer Security protocol as defined in RFC 2246 (TLS version 1.0) is “to provide privacy and data integrity between two communicating applications.” The TLS protocol ensures this by encrypting data so that any third party is unable to intercept the communication; it also authenticates the peers to verify their identity. By providing a secure channel of communication between two peers, TLS protocol protects the integrity of the message and ensures it is not being tampered.HistoryTLS and SSL are used interchangeably. TLS evolved from SSL protocol (SSL 3.0) that is no longer considered secure; vulnerabilities such as POODLE attack has demonstrated this. TLS has gone through two iterations, RFC 4346 (TLS 1.1) and RFC 5246 (TLS 1.2), with the latest update TLS 1.3 being a working draft.ArchitectureTLS lies in between the application and the transport layer.
The SSL/TLS master keys can be logged by mitmproxy so that external programs candecrypt SSL/TLS connections both from and to the proxy. Recent versions ofWireshark can use these log files to decrypt packets. See the Wireshark wiki for more information. Minecraft demo download pc on windows 10.
Key logging is enabled by setting the environment variable SSLKEYLOGFILE sothat it points to a writable text file:
export
this environment variable to make it persistent for all applications started from your current shell session.You can specify the key file path in Wireshark via Edit -> Preferences ->Protocols -> SSL -> (Pre)-Master-Secret log filename. If your SSLKEYLOGFILEdoes not exist yet, just create an empty text file, so you can select it inWireshark (or run mitmproxy to create and collect master secrets).
Note that SSLKEYLOGFILE is respected by other programs as well, e.g., Firefoxand Chrome. If this creates any issues, you can use MITMPROXY_SSLKEYLOGFILEinstead without affecting other applications.
