SSL encryption in IE7

[Pfipps]

IE7 finally includes AES encryption that both Opera and Firefox had for a couple of years. For example, yahoo mail and Gmail will

automatically use it in a browser that supports it. However, IE7 only seems to support AES 128, not 256. Is there a setting that can be changed

to enable it?

 

For example, in Amazon.com, Firefox will only use 128 bit RC4 (it is sufficient), but if you go to about:config,

search "ssl," and make

 

1)security.ssl3.rsa_rc4_128_sha

2)security.ssl3.rsa_rc4_128_md5

3)security.ssl3.rsa_fips_des_ede3_sha

4)security.ssl3.rsa_des_ede3_sha

5)security.ssl3.rsa_aes_128_sha

 

all false, then the Amazon.com certificate will use an AES 256 cipher. Some servers will not allow it, and you have to make 1) and 2) "true" again.

Oddly, my bank won't allow 256 bit AES ciphers while Gmail will .
