ngIRCd - Next Generation IRC Server (c)2001-2004 by Alexander Barton, alex@barton.de, http://www.barton.de/ ngIRCd is free software and published under the terms of the GNU General Public License. -- SSL.txt -- ngIRCd supports SSL/TLSv1 encrypted connections using the OpenSSL or gnutls library. Both encryped server <-> client and server <-> server links should work. BEWARE! The Code is mostly untested, use at your own risk! Example that creates a self-signed certificate and key (using OpenSSL): openssl req -newkey rsa:2048 -x509 -keyout server-key.pem \ -out server-cert.pem -days 1461 Example that creates DH parameters (optional): openssl dhparam -2 -out dhparams.pem 2048 Example that creates a self-signed certificate and key (using gnutls): certtool --generate-privkey --bits 2048 --outfile server-key.pem certtool --generate-self-signed --load-privkey server-key.pem \ --outfile server-cert.pem Example that creates DH parameters (optional): certtool --generate-dh-params --bits 2048 --outfile dhparams.pem Alternatively, you may use external programs/tools like stunnel to make it work: Stefan Sperling (stefan at binarchy dot net) mailed me the following text as a short "how-to", thanks Stefan! === snip === ! This guide applies to stunnel 4.x ! Put this in your stunnel.conf: [ircs] accept = 6667 connect = 6668 This makes stunnel listen for incoming connections on port 6667 and forward decrypted data to port 6668. We call the connection 'ircs'. Stunnel will use this name when logging connection attempts via syslog. You can also use the name in /etc/hosts.{allow,deny} if you run tcp-wrappers. To make sure ngircd is listening on the port where the decrypted data arrives, set Ports = 6668 in your ngircd.conf. Start stunnel and restart ngircd. That's it. Don't forget to activate ssl support in your irc client ;) === snip === -- $Id: SSL.txt,v 1.2 2004/12/27 01:11:40 alex Exp $
