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