gnutls_privkey_sign_data(3) gnutls gnutls_privkey_sign_data(3) NAME
gnutls_privkey_sign_data - API function SYNOPSIS
#include <gnutls/abstract.h> int gnutls_privkey_sign_data(gnutls_privkey_t signer, gnutls_digest_algorithm_t hash, unsigned int flags, const gnutls_datum_t * data, gnutls_datum_t * signature); ARGUMENTS
gnutls_privkey_t signer Holds the key gnutls_digest_algorithm_t hash should be a digest algorithm unsigned int flags Zero or on of gnutls_privkey_flags_t const gnutls_datum_t * data holds the data to be signed gnutls_datum_t * signature will contain the signature allocate with gnutls_malloc() DESCRIPTION
This function will sign the given data using a signature algorithm supported by the private key. Signature algorithms are always used together with a hash functions. Different hash functions may be used for the RSA algorithm, but only the SHA family for the DSA keys. You may use gnutls_pubkey_get_preferred_hash_algorithm() to determine the hash algorithm. RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. SINCE

gnutls_privkey_sign_raw_data(3) gnutls gnutls_privkey_sign_raw_data(3) NAME
gnutls_privkey_sign_raw_data - API function SYNOPSIS
#include <gnutls/abstract.h> int gnutls_privkey_sign_raw_data(gnutls_privkey_t key, unsigned flags, const gnutls_datum_t * data, gnutls_datum_t * signature); ARGUMENTS
gnutls_privkey_t key Holds the key unsigned flags should be zero const gnutls_datum_t * data holds the data to be signed gnutls_datum_t * signature will contain the signature allocate with gnutls_malloc() DESCRIPTION
This function will sign the given data using a signature algorithm supported by the private key. Note that this is a low-level function and does not apply any preprocessing or hash on the signed data. For example on an RSA key the input data should be of the DigestInfo PKCS 1 1.5 format. Use it only if you know what are you doing. Note this function is equivalent to using the GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA flag with gnutls_privkey_sign_hash(). RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. SINCE
