Hello All, Could someone please let me know what is the right way to enable null-ciphers in openssl. I want to do some performance evaluations with openssl and as a part of the exercise, want to tabulate performance with null encryption ciphers too.
Want to get this working with openssl s_server to begin with. I have come across various answers where people have suggested: 1. specify the cipher list using SSL_CTX_set_cipher_list with cipher list being only eNULL. 2. SSL_CTX_set_security_level with level=0. Have tried doing this from the client side but to no avail. On the server side, I have added -cipher "COMPLEMENTOFALL" to s_server to add the null ciphers. Is there a config option that needs to be enabled or a code change to go with ? thanks, -vishwas.
