EVP_SIGNATURE-ECDSA(7ossl) OpenSSL EVP_SIGNATURE-ECDSA(7ossl)
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>
"nonce-type" (OSSL_SIGNATURE_PARAM_NONCE_TYPE) <unsigned 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>
The parameters are described in provider-signature(7).
