6.2.2 DSA key parameters

A DSA private key is described by this S-expression:

(private-key
  (dsa
    (p p-mpi)
    (q q-mpi)
    (g g-mpi)
    (y y-mpi)
    (x x-mpi)))

p-mpi

DSA prime p.

q-mpi

DSA group order q (which is a prime divisor of p-1).

g-mpi

DSA group generator g.

y-mpi

DSA public key value y = g^x \bmod p.

x-mpi

DSA secret exponent x.

The public key is similar with "private-key" replaced by "public-key" and no x-mpi.
