gnutls_pk_algorithm_t gnutls_openpgp_crt_get_pk_algorithm(gnutls_openpgp_crt_t key, unsigned int * bits);
ARGUMENTS
gnutls_openpgp_crt_t key
is an OpenPGP key
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 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.
