Done

1. SSL IRC

• IPv6 works as well.

2. SSL botnet Linking

• Currently requires ssl.pem file
• Replaces old ghost protocol (custom AES). This makes the connection much more secure.

3. SSL partyline

• No extra ports needed
• openssl s_client -starttls pop3 -connect host:port

bryan here does not support CBC, nor did it have FiSH enabled. lolwut is using FiSH10's CBC mode.

The CBC is still vuln to replay attack as it does not take the previous data seen into account for its IV, which it really can't anyway as messages are not guaranteed to come through in the same order to all clients (even in a private message scenario).
