# gnutls\_sign\_supports\_pk\_algorithm(3)

API function

## NAME

gnutls\_sign\_supports\_pk\_algorithm - API function

## SYNOPSIS

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

**unsigned gnutls\_sign\_supports\_pk\_algorithm(gnutls\_sign\_algorithm\_t** *sign***, gnutls\_pk\_algorithm\_t** *pk***);**

## ARGUMENTS

- gnutls\_sign\_algorithm\_t sign

  is a signature algorithm

- gnutls\_pk\_algorithm\_t pk

  is a public key algorithm

## DESCRIPTION

This function returns non-zero if the public key algorithm corresponds to the given signature algorithm. That is, if that signature can be generated from the given private key algorithm.

## SINCE

3\.6.0

## RETURNS

return non-zero when the provided algorithms are compatible.
