NAME

gnutls_openpgp_privkey_get_subkey_pk_algorithm - return the subkey's PublicKey algorithm

SYNOPSIS

#include <gnutls/openpgp.h>

gnutls_pk_algorithm_t gnutls_openpgp_privkey_get_subkey_pk_algorithm(gnutls_openpgp_privkey_t key, unsigned int idx, unsigned int * bits);

ARGUMENTS

gnutls_openpgp_privkey_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 a negative value on error.

SINCE

2.4.0
