NAME

       EVP_SIGNATURE-DSA - The EVP_PKEY DSA signature implementation

DESCRIPTION

       Support for computing DSA signatures.  See EVP_PKEY-DSA(7) for information related to DSA keys.

   Signature Parameters
       The following signature parameters can be set using EVP_PKEY_CTX_set_params().  This may be called after
       EVP_PKEY_sign_init() or EVP_PKEY_verify_init(), and before calling EVP_PKEY_sign() or EVP_PKEY_verify().

       "digest" (OSSL_SIGNATURE_PARAM_DIGEST) <UTF8 string>
       "properties" (OSSL_SIGNATURE_PARAM_PROPERTIES) <UTF8 string>
           The settable parameters are described in provider-signature(7).

       The following signature parameters can be retrieved using EVP_PKEY_CTX_get_params().

       "algorithm-id" (OSSL_SIGNATURE_PARAM_ALGORITHM_ID) <octet string>
       "digest" (OSSL_SIGNATURE_PARAM_DIGEST) <UTF8 string>
           The gettable parameters are described in provider-signature(7).
