Hi,
I am building an application which needs TLSv1.2 protocol. I am getting
following issues with openssl-1.0.1c version:
Issue 1: openssl command errors out
=> openssl ciphers -v 'TLSv1.2'
Error in cipher list
47767988151392:error:140E6118:SSL routines:SSL_CIPHER_PROCESS_RULESTR:invalid
command:ssl_ciph.c:1170:
=>openssl ciphers -v 'TLSv1.2+HIGH:!AESGCM:!aNULL:!eNULL'
Error in cipher list
47393772139616:error:140E6118:SSL routines:SSL_CIPHER_PROCESS_RULESTR:invalid
command:ssl_ciph.c:1170:
Issue 2: SSL_CTX_set_cipher_list function errors out
if (!SSL_CTX_set_cipher_list(SSL_context,
"TLSv1.2+HIGH:!AESGCM:!aNULL:!eNULL")) // Function return 0 on error
{
printf("Can't set cipher list\n");
}
In openssl-1.0.1e version both the issues go away. Is this a bug? Is there any
way to fix the issue without upgrading the openssl library to new version?
Sam
