gnutls_privkey_sign_hash2 - API function
Синопсис (Synopsis)
#include <gnutls/abstract.h>
int gnutls_privkey_sign_hash2(gnutls_privkey_t signer,
gnutls_sign_algorithm_t algo, unsigned int flags, const
gnutls_datum_t * hash_data, gnutls_datum_t * signature);
Аргументы (Arguments)
gnutls_privkey_t signer
Holds the signer's key
gnutls_sign_algorithm_t algo
The signature algorithm used
unsigned int flags
Zero or one of gnutls_privkey_flags_t
const gnutls_datum_t * hash_data
holds the data to be signed
gnutls_datum_t * signature
will contain newly allocated signature
Описание (Description)
This function will sign the given hashed data using the specified
signature algorithm. This function is an enhancement of
gnutls_privkey_sign_hash(), as it allows utilizing a alternative
signature algorithm where possible (e.g, use an RSA key with
RSA-PSS).
The flags may be GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA. In that case
this function will ignore hash_algo and perform a raw PKCS1
signature. Note that this flag is supported since 3.6.9.
Note also that, not all algorithm support signing already hashed
data. When signing with Ed25519, gnutls_privkey_sign_data2()
should be used instead.
Возвращаемое значение (Return value)
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error value.
