* regarding DSS/DSA:
since you bring this up, i'd be curious to ask what's going on with
variations of DSS/DSA that allows for larger hashes & larger keys... i
guess i'm asking what the progress is being made within the cryptographic
community, and when that will bear fruit for "end users" of PGP/GPG.
* regarding ElGamal
i've also been curious what exactly makes ElGamal signing so tough...
based on my very limited understanding of the math involved, and reading
through applied cryptography, i guess i need a dumbed-down explanation.
* regarding Diffie-Hellman
it's my understanding that both ElGamal and DSS are variations of
Diffie-Hellman, and one of the advertised advantages of a DH based system
rather than an RSA system is that the primes used in a key are publicly
accessible for review (to verify that they're "good" primes)... in a
practical sense, how would one go about checking to see if whether or not
the primes are "good"?

"The limitation of riots, moral questions aside, is that
they cannot win and their participants know it. Hence,
rioting is not revolutionary but reactionary because it
invites defeat. It involves an emotional catharsis, but
it must be followed by a sense of futility."
