gnutls_x509_crt_get_pk_algorithm3
Api function
Usage
#include <gnutls/x509.h>
int gnutls_x509_crt_get_pk_algorithm(gnutls_x509_crt_t cert, unsigned int * bits);
Arguments
gnutls_x509_crt_t cert
|
should contain a |
|---|---|
unsigned int * bits
|
if bits is non null it will hold the size of the parameters' in bits |
Overview
This function will return the public key algorithm of an X.509 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.
Unknown/unsupported algorithms are mapped to GNUTLS_PK_UNKNOWN.
Returns
a member of the gnutls_pk_algorithm_t enumeration on success, or a negative error code on error.
