SYNOPSIS

#include <gnutls/openpgp.h>

gnutls_pk_algorithm_t gnutls_openpgp_crt_get_subkey_pk_algorithm(gnutls_openpgp_crt_t key, unsigned int idx, unsigned int * bits);

ARGUMENTS

gnutls_openpgp_crt_t key

is an OpenPGP key

unsigned int idx

is the subkey index

unsigned int * bits

if bits is non null it will hold the size of the parameters' in bits

DESCRIPTION

This function will return the public key algorithm of a subkey of an OpenPGP certificate.

If bits is non null, it should have enough size to hold the parameters size in bits. For RSA the bits returned is the modulus. For DSA the bits returned are of the public exponent.

RETURNS

a member of the gnutls_pk_algorithm_t enumeration on success, or GNUTLS_PK_UNKNOWN on error.

SINCE

2.4.0
