# Are there public $p$ and $q$ numbers for use in DSA?

There are many RFC documents giving large primes to use in Diffie-Hellman. However, I couldn't find standards on the $p$ and $q$ large primes used in the DSA signature scheme. This is proving to be a major obstacle in my own toy implementation of DSA, as generating these primes uses much messier math and code than the rest of the algorithm, and more places where I could make stupid mistakes that trash the security of the whole scheme.

Where can I find suitbale $p$ and $q$? They don't seem to need to be private, and frankly I'm kind of shocked that there aren't standard numbers for them to save people from needing to do the expensive calculations themselves.

NIST has published a bunch of them. –  CodesInChaos Nov 11 '13 at 7:09
Where? I can't find any. –  user54609 Nov 11 '13 at 13:10
