Requirement : The cipher suites(PSK-AES128-GCM-SHA256 and PSK-NULL-SHA256) are needed to be set during the handshake process between client and server in python(3.7) testframe using standard library ssl module(wrapper for openssl). My understanding is that PSK and weak ciphers are not enabled by default in openssl. Is my understanding correct? or these ciphers available by default?
so in case,if it is available, how can i set the ciphers and the project wants to use TLSv1.2 protocol.
