What you need is a Man-in-The-Middle proxy that acts like an SSL server from your application's perspective and from the server's perspective it works like the client. Decoding SBE (Simple Binary Encoding) messagesĬME works with data in CME MDP 3.0 and Streamlined formats. Even with the private key Wireshark can not decrypt the traffic in case a cipher with perfect forward secrecy (PFS) is used.

TLS traffic from Chrome, Firefox, and curl.Īlternatively, to debug FIX traffic it must be performed by TLS Decryption using an RSA private key. Troubleshooting Usage of (Pre)-Master-Secret (SSLKEYLOGFILE) to decrypt TLS FIX packetsĪs per Wireshark's official docs, the usage of (Pre)-Master-Secret (SSLKEYLOGFILE) is to decrypt HTTP + (over) TLS/SSL = HTTPS e.g. Once the connection will be established you will see decrypted traffic.If the connection is acting as an initiator it must have the server's private key to decrypt packets. If the session is established before starting the listening the traffic would not be decrypted.
