gnutls_openpgp_crt_get_subkey_pk_algorithm — API function


#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);


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


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.


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