I have an old file, I know what it contains, I know that this is encoding without a password, any privatekey and secretkey. This is some kind of encoded file/string, possibly converted several times.

Here's the encoded stroke - t‰„ЌЉ‚Ћ†™ќ‰ ›ќ–Ўљ§®°®¬·®»»·БАГЗЗАМНЛУТХЩЩТЬРуБЙРЪРдслТЫ

And perhaps there are two different encodings broken into parts.

First part - t‰„ЌЉ‚Ћ†™ќ‰ ›ќ–Ўљ§®°®¬·®»»·

Second part - БАГЗЗАМНЛУТХЩЩТЬРуБЙРЪРдслТЫ

Here's what might be contained here - LS80 095116A8A881F030A7A7292E 22042022 05:34:09:52:C9:86

Please help me find an encryption method, I will be very grateful. I apologize right away if this is written stupidly, I'm weak in cryptography

UPD : I found a program that processed this file. Here are the possible functions from IDA

    Hi, it's not clear what the question is and you are making a lot of assumptions by pasting stuff via your browser and expecting anyone to be able to help you from that. At a minimum you'd have to provide a hexdump or the Base32 (or similarly) encoded form of the data. By pasting some Cyrillic letters, you seem to have already assumed a certain encoding and removed the ability of all readers to look at raw data. Please update your question. Also, have you tried CyberChef?

    How do you know there's no password/key, and what makes you think LS80 ... might be the encoded data? Where's the file from? Any context would be helpful... Sep 16, 2023 at 10:52
  • @user7290573 I know what is in the file because I saw the source code of the application, what it contains in its key. There is no password or key, I talked with a person on the forum who extended this key for me. He doesn’t want to talk about the decryption method, he said it’s easy and you should try it yourself

    Uploading the file and the program/binary would indeed be very helpful. Sep 21, 2023 at 12:25
