What is SSL?
SSL stands for secure sockets layer which is a protocol developed by Netscape for transmitting private documents via the Internet. It works by using a private and public key to encrypt data over the connection. You have probably already used SSL when making an online purchase, or doing online banking. If you want a more in-depth explanation of how SSL works, you can go here: http://en.wikipedia.org/wiki/Secure_Sockets_Layer It is important to understand that when using IRC on a normal connection, the data is transmitted accross the internet in plaintext. This means that anyone could easily intercept your conversation. If you would rather that your conversations were kept private, then you should connect using SSL.
