gnutls_privkey_import_ext4(3) gnutls gnutls_privkey_import_ext4(3) NAME gnutls_privkey_import_ext4 - API function SYNOPSIS #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, un- signed int flags); ARGUMENTS 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 DESCRIPTION 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_IM- PORT_AUTO_RELEASE. Note that in contrast with the signing function of gnutls_privkey_im- port_ext3(), the signing functions provided to this function take explic- itly the signature algorithm as parameter and different functions are pro- vided 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 pro- hibited 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, GNUTLS_PRIVKEY_INFO_HAVE_SIGN_ALGO and GNUTLS_PRIVKEY_INFO_PK_ALGO_BITS. It must return -1 on unknown flags. RETURNS On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value. SINCE 3.6.0 REPORTING BUGS Report bugs to <bugs@gnutls.org>.
