  * @addtogroup x509_module X.509 module
  *
- * The X.509 module provides X.509 support which includes:
- * - X.509 certificate (CRT) reading (see \c x509parse_crt() and
- *   \c x509parse_crtfile()).
- * - X.509 certificate revocation list (CRL) reading (see \c x509parse_crl()
- *   and\c x509parse_crlfile()).
- * - X.509 (RSA and ECC) private key reading (see \c x509parse_key() and
- *   \c x509parse_keyfile()).
- * - X.509 certificate signature verification (see \c x509parse_verify())
- * - X.509 certificate writing and certificate request writing (see
- *   \c mbedtls_x509write_crt_der() and \c mbedtls_x509write_csr_der()).
+ * 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 X509 certificates just as a CA would do.
