# [NAME](#NAME)

gnutls\_privkey\_import\_ext - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <gnutls/abstract.h>**

**int gnutls\_privkey\_import\_ext(gnutls\_privkey\_t pkey, gnutls\_pk\_algorithm\_t pk, void * userdata, gnutls\_privkey\_sign\_func sign\_func, gnutls\_privkey\_decrypt\_func decrypt\_func, unsigned int flags);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_privkey\_t pkey](#gnutls_privkey_t)

The private key

[gnutls\_pk\_algorithm\_t pk](#gnutls_pk_algorithm_t)

The public key algorithm

[void * userdata](#void)

private data to be provided to the callbacks

[gnutls\_privkey\_sign\_func sign\_func](#gnutls_privkey_sign_func)

callback for signature operations

[gnutls\_privkey\_decrypt\_func decrypt\_func](#gnutls_privkey_decrypt_func)

callback for decryption operations

[unsigned int flags](#unsigned)

Flags for the import

# [DESCRIPTION](#DESCRIPTION)

This function will associate the given callbacks with the **gnutls\_privkey\_t** type. At least one of the two callbacks must be non-null.

Note that the signing function is supposed to "raw" sign data, i.e., without any hashing or preprocessing. In case of RSA the DigestInfo will be provided, and the signing function is expected to do the PKCS **1** 1.5 padding and the exponentiation.

See also **gnutls\_privkey\_import\_ext3()**.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error value.
