# gnutls\_privkey\_import\_ext2(3)

API function

## NAME

gnutls\_privkey\_import\_ext2 - API function

## SYNOPSIS

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

**int gnutls\_privkey\_import\_ext2(gnutls\_privkey\_t** *pkey***, gnutls\_pk\_algorithm\_t** *pk***, void \*** *userdata***, gnutls\_privkey\_sign\_func** *sign\_fn***, gnutls\_privkey\_decrypt\_func** *decrypt\_fn***, gnutls\_privkey\_deinit\_func** *deinit\_fn***, unsigned int** *flags***);**

## ARGUMENTS

- gnutls\_privkey\_t pkey

  The private key

- gnutls\_pk\_algorithm\_t pk

  The public key algorithm

- void \* userdata

  private data to be provided to the callbacks

- gnutls\_privkey\_sign\_func sign\_fn

  callback for signature operations

- gnutls\_privkey\_decrypt\_func decrypt\_fn

  callback for decryption operations

- gnutls\_privkey\_deinit\_func deinit\_fn

  a deinitialization function

- 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 two callbacks must be non-null. If a deinitialization function is provided then flags is assumed to contain **GNUTLS\_PRIVKEY\_IMPORT\_AUTO\_RELEASE**.

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

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

## SINCE

3\.1
