Tshark does not recognize Russian letters, what should I do?

Question

linux

I intercepted the travik, and let's say I need to find out the password or something else in Russian, Tshark reads Latin letters and numbers perfectly, but it denotes Russian letters as “ . . . . . . “
How can this be solved?

Answer 1

tshark also produces a hex dump.
It can be converted to its original form with the command . xxd -r
But with a blunt tshark -x | xxd -rone, only a small fragment is converted (presumably one package, I didn’t delve into it) and falls out, so you need to experiment, think a little and write a script. For example, pipe tshark output through awk or sed before feeding it to xxd.

and let's say I need to know the password

Don't count on it too much; except that the program that sends the password over the network was written by a schoolboy. In normal cases, a password hash is sent, or all authentication is wrapped in an encryption layer.
