Does IE6 Support AES 256 bit encryption?

Question

Will IE6 negotiate a 256 bit AES SSL connection if the server is capable?

Answer 1

Possibly, I can't work out for sure yet, but what I can tell you is AES256 appears to be restricted by US Export restrictions on high-security cryptography, and for this reason, some platforms may lack this capacity.

Also, upon further searching, msdn pages ( such as this one ) seem to point to AES support ( period! ) being only available since Vista / IE7.

No news yet whether or not MS decided to backport it, but it looks dubious.

Answer 2

Sometimes there is just a plain and simple way of finding out. If you look at the internet explorer help > about internet explorer, it will tell you the max cipher bits that it supports, and on IE6 its 128.
