29 * The X.509 module provides X.509 support for reading, writing and verification
32 * - X.509 certificate (CRT) reading (see \c mbedtls_x509_crt_parse(),
33 * \c mbedtls_x509_crt_parse_der(), \c mbedtls_x509_crt_parse_file()).
34 * - X.509 certificate revocation list (CRL) reading (see
35 * \c mbedtls_x509_crl_parse(), \c mbedtls_x509_crl_parse_der(),
36 * and \c mbedtls_x509_crl_parse_file()).
37 * - X.509 certificate signature verification (see \c
38 * mbedtls_x509_crt_verify() and \c mbedtls_x509_crt_verify_with_profile().
39 * - X.509 certificate writing and certificate request writing (see
40 * \c mbedtls_x509write_crt_der() and \c mbedtls_x509write_csr_der()).
42 * This module can be used to build a certificate authority (CA) chain and
43 * verify its signature. It is also used to generate Certificate Signing
44 * Requests and X.509 certificates just as a CA would do.
