NAME

       gnutls_x509_crt_get_pk_algorithm - return the certificate's PublicKey algorithm

SYNOPSIS

       #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 gnutls_x509_crt_t structure

       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 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.

RETURNS

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