int
gnutls_privkey_init (gnutls_privkey_t *key);

This function will initialize a private key object. The object can be used to generate, import, and perform cryptographic operations on the associated private key.

Note that when the underlying private key is a PKCS11 key (i.e., when imported with a PKCS11 URI), the limitations of gnutls_pkcs11_privkey_init() apply to this object as well. In versions of GnuTLS later than 3.5.11 the object is protected using locks and a single gnutls_privkey_t can be re-used by many threads. However, for performance it is recommended to utilize one object per key per thread.

                         unsigned int bits,
                         unsigned int flags);

This function will generate a random private key. Note that this function must be called on an initialized private key.

The flag GNUTLS_PRIVKEY_FLAG_PROVABLE instructs the key generation process to use algorithms like Shawe-Taylor (from FIPS PUB186-4) which generate provable parameters out of a seed for RSA and DSA keys. See gnutls_privkey_generate2() for more information.

Note that when generating an elliptic curve key, the curve can be substituted in the place of the bits parameter using the GNUTLS_CURVE_TO_BITS() macro. The input to the macro is any curve from gnutls_ecc_curve_t.

For DSA keys, if the subgroup size needs to be specified check the GNUTLS_SUBGROUP_TO_BITS() macro.

It is recommended to do not set the number of bits directly, use gnutls_sec_param_to_pk_bits() instead .

                          unsigned  data_size);

This function will generate a random private key. Note that this function must be called on an initialized private key.

The flag GNUTLS_PRIVKEY_FLAG_PROVABLE instructs the key generation process to use algorithms like Shawe-Taylor (from FIPS PUB186-4) which generate provable parameters out of a seed for RSA and DSA keys. On DSA keys the PQG parameters are generated using the seed, while on RSA the two primes. To specify an explicit seed (by default a random seed is used), use the data with a GNUTLS_KEYGEN_SEED type.

Note that when generating an elliptic curve key, the curve can be substituted in the place of the bits parameter using the GNUTLS_CURVE_TO_BITS() macro.

To export the generated keys in memory or in files it is recommended to use the PKCS#8 form as it can handle all key types, and can store additional parameters such as the seed, in case of provable RSA or DSA keys. Generated keys can be exported in memory using gnutls_privkey_export_x509(), and then with gnutls_x509_privkey_export2_pkcs8().

If key generation is part of your application, avoid setting the number of bits directly, and instead use gnutls_sec_param_to_pk_bits(). That way the generated keys will adapt to the security levels of the underlying GnuTLS library.

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 PKCS#1 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 PKCS#1 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, GNUTLS_PRIVKEY_INFO_HAVE_SIGN_ALGO and GNUTLS_PRIVKEY_INFO_PK_ALGO_BITS. It must return -1 on unknown flags.

                          gnutls_x509_crt_t *crt);

Converts the given gnutls_pcert_t type into a gnutls_x509_crt_t. This function only works if the type of pcert is GNUTLS_CRT_X509. When successful, the value written to crt must be freed with gnutls_x509_crt_deinit() when no longer needed.

gnutls_pcert_list_import_x509_raw ()

int
gnutls_pcert_list_import_x509_raw (gnutls_pcert_st *pcerts,
                                   unsigned int *pcert_max,

                                   unsigned int flags);

This function will import the provided DER or PEM encoded certificates to an already allocated set of gnutls_pcert_st structures. The structures must be deinitialized afterwards using gnutls_pcert_deinit(). pcert_list should contain space for at least pcert_list_size elements.

If the Certificate is PEM encoded it should have a header of "X509 CERTIFICATE", or "CERTIFICATE".
