/**
* @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) private key reading (see \c x509parse_key_rsa() and
- * \c x509parse_keyfile_rsa()).
+ * - 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 x509write_crt_der() and \c x509write_csr_der()).
*
* This module can be used to build a certificate authority (CA) chain and
- * verify its signature. It is also used to get a (RSA) private key for signing
- * and decryption.
+ * verify its signature. It is also used to generate Certificate Signing
+ * Requests and X509 certificates just as a CA would do.
