gnutls_pk_algorithm_t gnutls_openpgp_privkey_get_subkey_pk_algorithm(gnutls_openpgp_privkey_t key, unsigned int idx, unsigned int * bits);
is an OpenPGP key
is the subkey index
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 a negative error code on error.
