I am using OpenSSL (1.*) with Ngircd to enforce SSL connections. Is there a possibility that I can enforce certain ciphers or disable certain weak ciphers?
Perhaps use the 'stunnel' method for serving ngircd over SSL and disable weak ciphers through stunnel's configuration, see http://ngircd.barton.de/doc/SSL.txt
options = NO_SSLv2 ciphers = ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP
If you're using RHEL-derived distribution, perhaps enable FIPS mode to disable weak ciphers system-wide see section 7.2.1 in the below URL:
