- * RFC 3526 defines a number of standardized Diffie-Hellman groups

- * Some are included here for convenience.
+ * RFC 3526, RFC 5114 and RFC 7919 standardize a number of
+ * Diffie-Hellman groups, some of which are included here

+ * when configuring the Diffie-Hellman parameters by hand
+ * through \c mbedtls_ssl_conf_dh_param.
*
* Included are:
+ * RFC 5114 2.2. 2048-bit MODP Group with 224-bit Prime Order Subgroup
* RFC 3526 3. 2048-bit MODP Group
* RFC 3526 4. 3072-bit MODP Group
* RFC 3526 5. 4096-bit MODP Group
- * RFC 5114 2.2. 2048-bit MODP Group with 224-bit Prime Order Subgroup

* The constants with suffix "_p" denote the chosen prime moduli, while
* the constants with suffix "_g" denote the chosen generator
