The stuff in here is based on patches supplied to me by

The origional FIPE 180 used SHA-0 (FIPS 180) for its appendix 5
examples. This is an updated version that uses SHA-1 (FIPS 180-1)

APPENDIX 5. EXAMPLE OF THE DSA
This appendix is for informational purposes only and is not required to meet
the standard.
Let L = 512 (size of p). The values in this example are expressed in
hexadecimal notation. The p and q given here were generated by the prime
generation standard described in appendix 2 using the 160-bit SEED:
d5014e4b 60ef2ba8 b6211b40 62ba3224 e0427dd3
With this SEED, the algorithm found p and q when the counter was at 105.
x was generated by the algorithm described in appendix 3, section 3.1, using
the SHA to construct G (as in appendix 3, section 3.3) and a 160-bit XSEED:
XSEED =

x = G(t,XSEED) mod q
k was generated by the algorithm described in appendix 3, section 3.2, using
the SHA to construct G (as in appendix 3, section 3.3) and a 160-bit KSEED:
KSEED =
