NAME

gnutls_x509_crt_sign2 - API function

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crt_sign2(gnutls_x509_crt_t crt, gnutls_x509_crt_t issuer, gnutls_x509_privkey_t issuer_key, gnutls_digest_algorithm_t dig, unsigned int flags);

ARGUMENTS

gnutls_x509_crt_t crt: a certificate of type gnutls_x509_crt_t
gnutls_x509_crt_t issuer: is the certificate of the certificate issuer
gnutls_x509_privkey_t issuer_key: holds the issuer's private key
gnutls_digest_algorithm_t dig: The message digest to use, GNUTLS_DIG_SHA256 is a safe choice
unsigned int flags: must be 0

DESCRIPTION

This function will sign the certificate with the issuer's private key, and will copy the issuer's information into the certificate.

This must be the last step in a certificate generation since all the previously set parameters are now signed.

A known limitation of this function is, that a newly-signed certificate will not be fully functional (e.g., for signature verification), until it is exported an re-imported.

After GnuTLS 3.6.1 the value of dig may be GNUTLS_DIG_UNKNOWN, and in that case, a suitable but reasonable for the key algorithm will be selected.

RETURNS

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
