|

--fake-from-hex <value> Load fake packets for Fake Request Mode from HEX values (like 1234abcDEF).
|
||||
This option can be supplied multiple times, in this case each fake packet
|
||||
would be sent on every request in the command line argument order.
|
||||
--fake-with-sni <value> Generate fake packets for Fake Request Mode with given SNI domain name.
|
||||
The packets mimic Mozilla Firefox 130 TLS ClientHello packet
|
||||
(with random generated fake SessionID, key shares and ECH grease).
|
||||
Can be supplied multiple times for multiple fake packets.
|
||||
--fake-gen <value> Generate random-filled fake packets for Fake Request Mode, value of them
|
||||
(up to 30).
|
||||
--fake-resend <value> Send each fake packet value number of times.
