+=head2 DSA key validation
+
+For DSA keys, L<EVP_PKEY_param_check(3)> behaves in the following way:
+The OpenSSL FIPS provider conforms to the rules within the FIPS186-4
+standard for FFC parameter validation. For backwards compatibility the OpenSSL
+default provider uses a much simpler check (see below) for parameter validation,
+unless the seed parameter is set.
+
+For DSA keys, L<EVP_PKEY_param_check_quick(3)> behaves in the following way:
+A simple check of L and N and partial g is performed. The default provider
+also supports validation of legacy "fips186_2" keys.
+
+For DSA keys, L<EVP_PKEY_public_check(3)>, L<EVP_PKEY_private_check(3)> and
+L<EVP_PKEY_pairwise_check(3)> the OpenSSL default and FIPS providers conform to
+the rules within SP800-56Ar3 for public, private and pairwise tests respectively.
