Yes, seems relevant... but I am blind beyond this. It clearly mention the default cipher ,and indeed ,i do get this with default keys/certs generated by FS script Also, for ECDHE-ECDSA like ciphers, it is said , to create elliptic curved keys in Public n private keys, which is not the case with those of created with FS script. But lets say, i manage to create keys with elliptic curves algo, how could the mentioned C file be helpful for my approach. And what format of cipher it accepts (as it doesn't seems to work after just replacing the Default string with required cipher string ) -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/SIP-S-and-openssl-tp7591496p75...
