I am using apache. I guess OpenSSL library is used.

Thank you. Okay, for now, I think I'll be usin IDEA for my SSL site 
because it's faster (I am not sure if AES is supported by IE, so I just 
ignore it). What do I say in user's operation hand book? Since 3DES and 
IDEA are both strong, I can just quote what Bruce Schneier said about 
3DES and say IDEA is similar.

I heard from gentoo-user list that one of Bruce's book has easy 
explanation of each cipher's strength:
http://www.schneier.com/book-applied-toc.html

However I won't buy a book and have it shipped to China just for one 
line of quote.
