EVP_SIGNATURE-ECDSA(7ssl) OpenSSL EVP_SIGNATURE-ECDSA(7ssl)

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).

EVP_PKEY_CTX_set_params(3), EVP_PKEY_sign(3), EVP_PKEY_verify(3), provider-signature(7),
