 * `padencap`. Padding extension is extended by original TLS Client Hello size (including multi packet variation with kyber). Padding extension is added to the end if not present, otherwise it must be the last extension. All lengths are increased. Fake size is not changed. Can be useful if DPI does not analyze sequence numbers properly. Applied on every request.

 By default if custom fake is not defined `rnd,rndsni,dupsid` mods are applied. If defined - `none`.
 This behaviour is compatible with previous versions with addition of `dupsid`.

-If TLS mod is enabled and there're multiple TLS fakes, all valid TLS Client Hello fakes are modified.
-If there's no TLS Client Hello program exits with error.
+If multiple TLS fakes are present each one takes the last mod.
+If a mod is specified after fake it replaces previous mod.
+This way it's possible to use different mods for every TLS fake.

+If a mod is set to non-TLS fake it causes error. Use `--dpi-desync-fake-tls-mod=none'.
