# gnutls\_crypto\_pk\_register2(3)

register a public key interface

## NAME

gnutls\_crypto\_pk\_register2 - register a public key interface

## SYNOPSIS

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

**int gnutls\_crypto\_pk\_register2(int** *priority***, int** *version***, gnutls\_crypto\_pk\_st \*** *s***);**

## ARGUMENTS

- int priority

  is the priority of the interface

- int version

  should be set to **GNUTLS\_CRYPTO\_API\_VERSION**

- gnutls\_crypto\_pk\_st \* s

  is a structure holding new interface's data

## DESCRIPTION

This function will register an interface for gnutls to operate on public key operations. Any interface registered will override the included interface. The interface with the lowest priority will be used by gnutls.

Note that the bigint interface must interoperate with the bigint interface. Thus if this interface is updated the **gnutls\_crypto\_bigint\_register()** should also be used.

This function should be called before **gnutls\_global\_init()**.

For simplicity you can use the convenience **gnutls\_crypto\_pk\_register()** macro.

## RETURNS

**GNUTLS\_E\_SUCCESS** on success, otherwise an error.

## SINCE

2\.6.0
