EVP_SIGNATURE-DSA - The EVP_PKEY DSA signature implementation
Support for computing DSA signatures. The signature produced with
EVP_PKEY_sign(3) is DER encoded ASN.1 in the form described in RFC
3279, section 2.2.2. 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).
