gnutls_certificate_set_x509_simple_pkcs12_mem — API function


#include <gnutls/gnutls.h>
int gnutls_certificate_set_x509_simple_pkcs12_mem( gnutls_certificate_credentials_t res,
  const gnutls_datum_t * p12blob,
  gnutls_x509_crt_fmt_t type,
  const char * password);


gnutls_certificate_credentials_t res

is a gnutls_certificate_credentials_t structure.

const gnutls_datum_t * p12blob

the PKCS12 blob.

gnutls_x509_crt_fmt_t type

is PEM or DER of the pkcs12file .

const char * password

optional password used to decrypt PKCS12 file, bags and keys.


This function sets a certificate/private key pair and/or a CRL in the gnutls_certificate_credentials_t structure. This function may be called more than once (in case multiple keys/certificates exist for the server).

Encrypted PKCS12 bags and PKCS8 private keys are supported. However, only password based security, and the same password for all operations, are supported.

PKCS12 file may contain many keys and/or certificates, and there is no way to identify which key/certificate pair you want. You should make sure the PKCS12 file only contain one key/certificate pair and/or one CRL.

It is believed that the limitations of this function is acceptable for most usage, and that any more flexibility would introduce complexity that would make it harder to use this functionality at all.


GNUTLS_E_SUCCESS (0) on success, or a negative error code.
