Hi Dave,

>I'm guessing ADH means Anonymous Diffie Hellman, right?  and AES256 is the
AES encryption cipher w/ a 256 bit cipher key?
Right

 TLS cipher suites are defined in RFC5246.

They defines the Key exchange algorithm, the symmetric encryption, and the
hash function.

Example:

TLS1_TXT_DHE_DSS_WITH_RC4_128_SHA

Key exchange is DHE authenticated with DSS
RC4 is the symmetric encryption
SHA is the hash function.

>What is DHE_DSS vs. DHE_RSA and things like that?
DHE should be authenticated, with RSA- or DSS-based certificates (or
preshared keys-see RFC4279))

>Can anybody point me to where these are defined?
Most of them are defined in RFC 5246

>Is there any benefit of one over the other?
for PFS, usually we use DHE, but DH is more expensive (execution time) than
RSA
Best regards,
Badra
