bin file extracted from a ZXHN H168N V3.1. RouterPassView is able to decrypt the file successfully but the tool can't re-encrypt the file, it gave me some info about the method used to decrypt here they are

File Type: 29 Encrypted Data Start Position: 227 Encryption Algorithm: AES-128 Encryption Key: 34303263333864653339626564363635 Compression: zlib/deflate

am a noob when it comes to this stuff so idk how to code my own tool does anyone know a tool that i could use to decrypt and re-encrypt the file

You can use the zcu module (written by Mark Streetster) to decrypt/encrypt your config.bin file.

  • i tried that but it didn't work even when i specified the key it gave me an error that i can't remember what type/version should i use – Ammar Yasser Nov 28 '20 at 21:49
  • @Ammar Yasser If you want to upload a copy of your config.bin file I will check it out. – user2017 Nov 29 '20 at 22:39

They use zlib encryption in the firmware, have you tried encrypting it with zlib and repack it with binwalk squashfs?

Edit: would you mind sharing decrypted firmware? So, I’ll have a look into it.
