6 - The B<EVP_PKEY> DSA signature implementation
10 Support for computing DSA signatures.
11 See L<EVP_PKEY-DSA(7)> for information related to DSA keys.
13 =head2 Signature Parameters
15 The following signature parameters can be set using EVP_PKEY_CTX_set_params().
16 This may be called after EVP_PKEY_sign_init() or EVP_PKEY_verify_init(),
17 and before calling EVP_PKEY_sign() or EVP_PKEY_verify().
21 =item "digest" (B<OSSL_SIGNATURE_PARAM_DIGEST>) <UTF8 string>
23 =item "properties" (B<OSSL_SIGNATURE_PARAM_PROPERTIES>) <UTF8 string>
25 The settable parameters are described in L<provider-signature(7)>.
29 The following signature parameters can be retrieved using
30 EVP_PKEY_CTX_get_params().
34 =item "algorithm-id" (B<OSSL_SIGNATURE_PARAM_ALGORITHM_ID>) <octet string>
36 =item "digest" (B<OSSL_SIGNATURE_PARAM_DIGEST>) <UTF8 string>
38 The gettable parameters are described in L<provider-signature(7)>.
