+
+EVP_PKEY-DSA, EVP_KEYMGMT-DSA, EVP_PKEY-DH, EVP_KEYMGMT-DH
+- EVP_PKEY DSA and DH keytype and algorithm support
+
+=head1 DESCRIPTION
+
+The B<DSA> and B<DH> keytypes are implemented in OpenSSL's default and FIPS
+providers.
+The implementations support the basic DSA and DH keys, containing the public
+and private keys I<pub> and I<priv> as well as the three domain parameters
+I<p>, I<q> and I<g>.
+
+=head2 Common DSA / DH parameters
+
+In addition to the common parameters that all keytypes should support (see
+L<provider-keymgmt(7)/Common parameters>), the B<DSA> and B<DH> keytype
+implementations support the following.
+
+=over 4
+
+=item "pub" (B<OSSL_PKEY_PARAM_PUB_KEY>) <unsigned integer>
+
+The public key value.
+
+=item "priv" (B<OSSL_PKEY_PARAM_PRIV_KEY>) <unsigned integer>
+
+The private key value.
+
+=item "p" (B<OSSL_PKEY_PARAM_FFC_P>) <unsigned integer>
+
+A DSA or Diffie-Hellman "p" value.
+
+=item "q" (B<OSSL_PKEY_PARAM_FFC_Q>) <unsigned integer>
+
+A DSA or Diffie-Hellman "q" value.
+
+=item "g" (B<OSSL_PKEY_PARAM_FFC_G>) <unsigned integer>
+
+A DSA or Diffie-Hellman "g" value.
