EVP_SIGNATURE-ECDSA - The EVP_PKEY ECDSA signature implementation.
Support for computing ECDSA signatures. See
EVP_PKEY-EC(7) for
information related to EC 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>
- These 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 parameters are described in
provider-signature(7).
