DSS signatures and keys

1998-05-13 06:23:36
Folks,

Is there a document which describes exactly how DSS signature and
certificate data should be formatted (i.e. the organization of data within
a "SignatureValue", etc.)?

Specifically, in handling signed messages, we have:

To verify the contents of a DSA signed message on the other end you need 
three values P, Q, G and the Public Key. The values of P, Q and G must be 
the same as those used to sign the message.  (where the Public Key is 
derived from the P,Q, and G values and the private key).

How are the P, Q and G values communicated?  Are they part of the
signature, the public key or something else?
