+EVP_PKEY_CTX_set_dsa_paramgen_bits() sets the number of bits used for DSA
+parameter generation to B<nbits>. If not specified, 2048 is used.
+
+EVP_PKEY_CTX_set_dsa_paramgen_q_bits() sets the number of bits in the subprime
+parameter I<q> for DSA parameter generation to I<qbits>. If not specified, 224
+is used. If a digest function is specified below, this parameter is ignored and
+instead, the number of bits in I<q> matches the size of the digest.
+
+EVP_PKEY_CTX_set_dsa_paramgen_md() sets the digest function used for DSA
+parameter generation to I<md>. If not specified, one of SHA-1, SHA-224, or
+SHA-256 is selected to match the bit length of I<q> above.
+
+EVP_PKEY_CTX_set_dsa_paramgen_md_props() sets the digest function used for DSA
+parameter generation using I<md_name> and I<md_properties> to retrieve the
+digest from a provider.
+If not specified, I<md_name> will be set to one of SHA-1, SHA-224, or
+SHA-256 depending on the bit length of I<q> above. I<md_properties> is a
+property query string that has a default value of '' if not specified.
+
+EVP_PKEY_CTX_set_dsa_paramgen_gindex() sets the I<gindex> used by the generator
+G. The default value is -1 which uses unverifiable g, otherwise a positive value
+uses verifiable g. This value must be saved if key validation of g is required,
+since it is not part of a persisted key.
+
+EVP_PKEY_CTX_set_dsa_paramgen_seed() sets the I<seed> to use for generation
+rather than using a randomly generated value for the seed. This is useful for
+testing purposes only and can fail if the seed does not produce primes for both
+p & q on its first iteration. This value must be saved if key validation of
+p, q, and verifiable g are required, since it is not part of a persisted key.
+
+EVP_PKEY_CTX_set_dsa_paramgen_type() sets the generation type to use FIPS186-4
+generation if I<name> is "fips186_4", or FIPS186-2 generation if I<name> is
+"fips186_2". The default value for the default provider is "fips186_2". The
+default value for the FIPS provider is "fips186_4".
