  *  If return value is SECSuccess, then *pResult has these meanings:
  *       SECSuccess: PQGParams are valid.

  * Verify the following 12 facts about PQG counter SEED g and h
- * 1.  Q is 160 bits long.
- * 2.  P is one of the 9 valid lengths.
- * 3.  G < P
- * 4.  P % Q == 1
- * 5.  Q is prime
- * 6.  P is prime
- * Steps 7-12 are done only if the optional PQGVerify is supplied.
- * 7.  counter < 4096
- * 8.  g >= 160 and g < 2048   (g is length of seed in bits)
- * 9.  Q generated from SEED matches Q in PQGParams.
- * 10. P generated from (L, counter, g, SEED, Q) matches P in PQGParams.
- * 11. 1 < h < P-1
- * 12. G generated from h matches G in PQGParams.
+ * These tests are specified in FIPS 186-3 Appendix A.1.1.1, A.1.1.3, and A.2.2
+ * PQG_VerifyParams in softoken/freebl will automatically choose the
