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.
Algorithm Names
In this list, names are grouped together to signify that they are the same algorithm having multiple names. This also includes the OID in canonical decimal form (which means that they are possible to fetch if the caller has a mere OID which came out in this form after a call to OBJ_obj2txt(3)).

ECDSA signature schemes with diverse message digest algorithms. They are all supported explicitly fetched with EVP_PKEY_sign_init_ex2(3) and EVP_PKEY_sign_message_init(3).
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 two are not supported with the ECDSA signature schemes that already include a message digest algorithm, See "Algorithm Names" above.
- "nonce-type" (OSSL_SIGNATURE_PARAM_NONCE_TYPE) <unsigned integer>
- "key-check" (OSSL_SIGNATURE_PARAM_FIPS_KEY_CHECK) <integer>
- "digest-check" (OSSL_SIGNATURE_PARAM_FIPS_DIGEST_CHECK) <integer>
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>
- "nonce-type" (OSSL_SIGNATURE_PARAM_NONCE_TYPE) <unsigned integer>
- "fips-indicator" (OSSL_SIGNATURE_PARAM_FIPS_APPROVED_INDICATOR) <integer>
- "verify-message" (OSSL_SIGNATURE_PARAM_FIPS_VERIFY_MESSAGE <integer>
The parameters are described in provider-signature(7).
