NAME

       EVP_SIGNATURE-ECDSA - The EVP_PKEY ECDSA signature implementation.


DESCRIPTION

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

   ECDSA 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>
           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).
