+supplied to me by Wei Dai
+--
+ 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 =
+
+ bd029bbe 7f51960b cf9edb2b 61f06f0f eb5a38b6
+
+t =
+ 67452301 EFCDAB89 98BADCFE 10325476 C3D2E1F0
+
+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 =
+
+ 687a66d9 0648f993 867e121f 4ddf9ddb 01205584
+
+t =
+ EFCDAB89 98BADCFE 10325476 C3D2E1F0 67452301
+
+k = G(t,KSEED) mod q
