If the client and server negotiate the use of Diffie Hellman (which again is mandatory for TLS 1.3,) then you can not decrypt data connections with the cert and the private key for the server even if you work through the issues you have in your code. SSL/TLS certificates are only used for authentication in TLS 1.3 and in lower versions unless you configure the server to only support RSA key exchange your server is going to pick Diffie Hellman. What you are trying to do is not going to work. Then this is possible but who knows the codes? Tanx.Įxample Groups That SOLVE this but not share their code: please and please if you have the answer then share the code snippet references, if not leave it, because some groups solve this but they don't share their solutions. NOTE: I don't need Philosophy, I have so many reference about that, I know so many developers say that this is impossible and make their Philosophy logics for it. If you have any solution then please share it and I will test and share the result with no negative score. #dec2 = k.decrypt(bytes(pkt.payload).decode('UTF8', 'replace'), t='oaep') #dec2 = k.decrypt(bytes(pkt.payload), t='oaep') # and i was try 'pss' instead of 'oaep' but same errorĭec2 = k.decrypt(pkt.payload, t='oaep') # any 3 below commands go in same error # If ('TLSEncryptedContent' in str(type(pkt.payload))): If (src='my-server-ip') or (dst='my-server-ip'): #M = bytes('message to be encrypted'.encode()) Value Error: ciphertext length must be equal to key size import os, sys Then I have the original international registered certificate ( TLS1.3) files for my domain.Īnd it must be so much easy to do this with scapy BUT I can not find any solution anywhere and this is so crazy.įor example I was try these solutions, but they not working with no bug and crash :įinaly I was writting a sample code BUT it raising below error and I try too much to fix it but cant understand the problem and clear solution: I want to decrypt HTTPS traffic for my domain on my server with scapy.
