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:

Hi Nathan
I rather want to keep stunnel work arounds out of the options.. It would be a nice feature to add to the new ngircd release ;)
