NAME

6       EVP_SIGNATURE-ECDSA - The EVP_PKEY ECDSA signature implementation.
7

DESCRIPTION

9       Support for computing ECDSA signatures.  See EVP_PKEY-EC(7) for
10       information related to EC keys.
11
12   ECDSA Signature Parameters
13       The following signature parameters can be set using
14       EVP_PKEY_CTX_set_params().  This may be called after
15       EVP_PKEY_sign_init() or EVP_PKEY_verify_init(), and before calling
16       EVP_PKEY_sign() or EVP_PKEY_verify().
17
18       "digest" (OSSL_SIGNATURE_PARAM_DIGEST) <UTF8 string>
19       "properties" (OSSL_SIGNATURE_PARAM_PROPERTIES) <UTF8 string>
20           These parameters are described in provider-signature(7).
21
22       The following signature parameters can be retrieved using
23       EVP_PKEY_CTX_get_params().
24
25       "algorithm-id" (OSSL_SIGNATURE_PARAM_ALGORITHM_ID) <octet string>
26       "digest" (OSSL_SIGNATURE_PARAM_DIGEST) <UTF8 string>
27           The parameters are described in provider-signature(7).
