gnutls_x509_crt_sign2 — API function
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);
- 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
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.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
