gnutls_x509_crt_init ()

int         gnutls_x509_crt_init            (gnutls_x509_crt_t *cert);

This function will initialize an X.509 certificate structure.

cert :
Returns :

gnutls_x509_crt_deinit ()

void        gnutls_x509_crt_deinit          (gnutls_x509_crt_t cert);

This function will deinitialize a CRL structure.

cert :

gnutls_x509_crt_import ()

int         gnutls_x509_crt_import          (gnutls_x509_crt_t cert,

                                             gnutls_x509_crt_fmt_t format);

This function will convert the given DER or PEM encoded Certificate to the native gnutls_x509_crt_t format. The output will be stored in cert.

If the Certificate is PEM encoded it should have a header of "X509 CERTIFICATE", or "CERTIFICATE".

cert :

Returns :

gnutls_x509_crt_export ()

int         gnutls_x509_crt_export          (gnutls_x509_crt_t cert,

                                             size_t *output_data_size);

This function will export the certificate to DER or PEM format.

If the buffer provided is not long enough to hold the output, then GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

If the structure is PEM encoded, it will have a header of "BEGIN CERTIFICATE".

In case of failure a negative value will be returned, and 0 on success.

This function will try to verify the given certificate list and return its status. Note that expiration and activation dates are not checked by this function, you should check them using the appropriate functions.

If no flags are specified (0), this function will use the basicConstraints (2.5.29.19) PKIX extension. This means that only a certificate authority is allowed to sign a certificate.

You must also check the peer's name in order to check if the verified certificate belongs to the actual peer.

The certificate verification output will be put in verify and will be one or more of the gnutls_certificate_status_t enumerated elements bitwise or'd. For a more detailed verification status use gnutls_x509_crt_verify() per list element.

GNUTLS_CERT_INVALID\: the certificate chain is not valid.

GNUTLS_CERT_REVOKED\: a certificate in the chain has been revoked.

This function will convert the given DER or PEM encoded PKCS8 2.0 encrypted key to the native gnutls_x509_privkey_t format. The output will be stored in key. Currently only RSA keys can be imported, and flags can only be used to indicate an unencrypted key.

The password can be either ASCII or UTF-8 in the default PBES2 encryption schemas, or ASCII for the PKCS12 schemas.

If the Certificate is PEM encoded it should have a header of "ENCRYPTED PRIVATE KEY", or "PRIVATE KEY". You only need to specify the flags if the key is DER encoded.

gnutls_x509_crq_export ()

int         gnutls_x509_crq_export          (gnutls_x509_crq_t crq,
                                             gnutls_x509_crt_fmt_t format,

                                             size_t *output_data_size);

This function will export the certificate request to a PKCS10

If the buffer provided is not long enough to hold the output, then GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

If the structure is PEM encoded, it will have a header of "BEGIN NEW CERTIFICATE REQUEST".

In case of failure a negative value will be returned, and 0 on success.
