|  | * @addtogroup x509_module X.509 module | 
|  | * | 
|  | * The X.509 module provides X.509 support for reading, writing and verification | 
|  | * of certificates. | 
|  | * In summary: | 
|  | *   - X.509 certificate (CRT) reading (see \c mbedtls_x509_crt_parse(), | 
|  | *     \c mbedtls_x509_crt_parse_der(), \c mbedtls_x509_crt_parse_file()). | 
|  | *   - X.509 certificate revocation list (CRL) reading (see | 
|  | *     \c mbedtls_x509_crl_parse(), \c mbedtls_x509_crl_parse_der(), | 
|  | *     and \c mbedtls_x509_crl_parse_file()). | 
|  | *   - X.509 certificate signature verification (see \c | 
|  | *     mbedtls_x509_crt_verify() and \c mbedtls_x509_crt_verify_with_profile(). | 
|  | *   - X.509 certificate writing and certificate request writing (see | 
|  | *     \c mbedtls_x509write_crt_der() and \c mbedtls_x509write_csr_der()). | 
|  | * | 
|  | * This module can be used to build a certificate authority (CA) chain and | 
|  | * verify its signature. It is also used to generate Certificate Signing | 
|  | * Requests and X.509 certificates just as a CA would do. |
