gnutls_privkey_import_ext4(3) gnutls gnutls_privkey_import_ext4(3)
gnutls_privkey_import_ext4 - API function
#include <gnutls/abstract.h>
int gnutls_privkey_import_ext4(gnutls_privkey_t pkey, void *
userdata, gnutls_privkey_sign_data_func sign_data_fn,
gnutls_privkey_sign_hash_func sign_hash_fn,
gnutls_privkey_decrypt_func decrypt_fn, gnutls_privkey_deinit_func
deinit_fn, gnutls_privkey_info_func info_fn, unsigned int flags);
gnutls_privkey_t pkey
The private key
void * userdata
private data to be provided to the callbacks
gnutls_privkey_sign_data_func sign_data_fn
callback for signature operations (may be NULL)
gnutls_privkey_sign_hash_func sign_hash_fn
callback for signature operations (may be NULL)
gnutls_privkey_decrypt_func decrypt_fn
callback for decryption operations (may be NULL)
gnutls_privkey_deinit_func deinit_fn
a deinitialization function
gnutls_privkey_info_func info_fn
returns info about the public key algorithm (should not
be NULL)
unsigned int flags
Flags for the import
This function will associate the given callbacks with the
gnutls_privkey_t type. At least one of the callbacks must be
non-null. If a deinitialization function is provided then flags is
assumed to contain GNUTLS_PRIVKEY_IMPORT_AUTO_RELEASE.
Note that in contrast with the signing function of
gnutls_privkey_import_ext3(), the signing functions provided to this
function take explicitly the signature algorithm as parameter and
different functions are provided to sign the data and hashes.
The sign_hash_fn is to be called to sign pre-hashed data. The input
to the callback is the output of the hash (such as SHA256)
corresponding to the signature algorithm. For RSA PKCS1 signatures,
the signature algorithm can be set to GNUTLS_SIGN_RSA_RAW, and in
that case the data should be handled as if they were an RSA PKCS1
DigestInfo structure.
The sign_data_fn is to be called to sign data. The input data will
be he data to be signed (and hashed), with the provided signature
algorithm. This function is to be used for signature algorithms like
Ed25519 which cannot take pre-hashed data as input.
When both sign_data_fn and sign_hash_fn functions are provided they
must be able to operate on all the supported signature algorithms,
unless prohibited by the type of the algorithm (e.g., as with
Ed25519).
The info_fn must provide information on the signature algorithms
supported by this private key, and should support the flags
GNUTLS_PRIVKEY_INFO_PK_ALGO and GNUTLS_PRIVKEY_INFO_HAVE_SIGN_ALGO.
It must return -1 on unknown flags.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error value.
