4.1.1.2 Importing an X.509 certificate

The certificate structure should be initialized using gnutls_x509_crt_init, and a certificate structure can be imported using gnutls_x509_crt_import.

int gnutls_x509_crt_init (gnutls_x509_crt_t * cert)

int gnutls_x509_crt_import (gnutls_x509_crt_t cert, const gnutls_datum_t * data, gnutls_x509_crt_fmt_t format)

void gnutls_x509_crt_deinit (gnutls_x509_crt_t cert)

In several functions an array of certificates is required. To assist in initialization and import the following two functions are provided.

int gnutls_x509_crt_list_import (gnutls_x509_crt_t * certs, unsigned int * cert_max, const gnutls_datum_t * data, gnutls_x509_crt_fmt_t format, unsigned int flags)

int gnutls_x509_crt_list_import2 (gnutls_x509_crt_t ** certs, unsigned int * size, const gnutls_datum_t * data, gnutls_x509_crt_fmt_t format, unsigned int flags)

In all cases after use a certificate must be deinitialized using gnutls_x509_crt_deinit. Note that although the functions above apply to gnutls_x509_crt_t structure, similar functions exist for the CRL structure gnutls_x509_crl_t.
