=head1 NAME
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.
