    Never used PS sadly but I think most anti hacks should work the same. get the CRC of the files you want to protect and save the data on wherever PS saves them.

    for what mu season are you talking about (client) ?
    you must find a program that encrypts the client side files u want to Protect and decrypts it only after main.exe is runned so ppl can't steal these files or modify them at all, ofcourse plain CRC is fine too but ppl can still steal your files, so therefore best thing is to have the best antihack protection only on server side based with like launcher that does crc etc and not antihack, antihack is another story and if u have latest season mu u dont need it necessarily right away

    -> bullshit, you can copy the files anyway while the game is running

    CRC to detect changes in files is bullshit as well, because it can be circumvented too easily. I can't take any antihack vendor serious which is using CRC to check file integrity. They should use cryptographic hash algorithms instead (SHA256, for example).

    Anyway... client side anti hack is either not secure or too intrusive to the system which creates instability. Best protection is on the server-side ;-)

    Chill Mr nevS, whatever you call that as 'CRC' i have never labeled it my self and never said is the absolute solution because no one did it yet that shared a solution or an example of a server that has this working properly, so if that's not possible then better bring your own idea to the table and help us since you are the Developer here lol, stop playing smart on us, there's no reason to compete.

    Re: Crc

    I'm chilled xD Wasn't a critique to you, but in general. CRC is bullshit and people on this forum still believe it protects against anything. There was a discussion about it a few years ago: https://forum.ragezone.com/f197/prot...source-863822/

    My ideas to protect the client/server:
    * Very simple detection mechanisms to detect cheats. Not too intrusive, just to keep the noob cheaters and maybe bots out.
    * Checks on the server side, maybe even a trained AI which can detect suspicious behavior, e.g. too low delays between attacks, too fast moving etc. As long as the client behaves legit, why care about protecting the client side at all?

    And no, I don't have interest in developing anything of that.

    Re: Crc

    Haha always as even being a player knowing some friends who cheat, someone who intends to really cheat will find a way no matter what, also I agree with what nevS said, I'm not a dev or a security expert but I do know CRC can be spoofed, replaced and emulated.

    But on topic to the OP, though, I think you should just follow what maker of the anti-cheat left, maybe there's some instructions., I think there's some premium anti cheats as well but I never used those and people I think who paid won't help you here unless you're lucky.

    Super slow reply and they are really not promising but its does have more sofiscated system to bypass vs PS Sistemas.

    Also your player might be prompt that it a virus and need might force them to add it as an exception.
