I have now uploaded my sycript to generate the pms file out of the tcpdump file with enabled sslprovider. This script works for all TLS versions and decrypts clientside and serverside traffic. 

I use this script in my daily job and I hope it could help other people also!

Juergen_Mang

thank you for sharing your script.

Sorry to bump this old thread.

For some reason only the client side traffic get's decrypted. Communication between LTM and nodes are still encrypted. I'm using the tcpdump command as mentioned in your github.

Any idea?
