Hi,
I add a few bullets to the list.
you should also check the handshake. Are the DES, RC4 or no-encryption
options enabled? What are the defaults?
If clients and server are fixed, or added in a controlled way, you may
want to add the requirement of mutual authentication!
What about random number generation? Can one force the server to reuse
symmetric keys? Are there any race conditions in the implementation?
On the other hand, if the crypto has been implemented from scratch, then
you might want to check it for binary vulnerabilities. Else, if you
match this crypto with a known library, do check if there are any
reported bugs for this library.
Cheers,
Ariel
