gnutls_x509_c..._pk_algorithm(3) gnutls gnutls_x509_c..._pk_algorithm(3)
gnutls_x509_crt_get_pk_algorithm - API function
#include <gnutls/x509.h>
int gnutls_x509_crt_get_pk_algorithm(gnutls_x509_crt_t cert,
unsigned int * bits);
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
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 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.
a member of the gnutls_pk_algorithm_t enumeration on success, or
a negative error code on error.
