The encryption key is often derived from the router’s MAC address, serial number, or a hardcoded manufacturer string. Step-by-Step Decryption Methods

When you back up a ZTE router's configuration via its web interface, you typically get a file named config.bin . This is not a simple text file; it's a binary blob containing everything from your Wi-Fi password to your ISP's hidden administrative access credentials. Inside, it usually holds an XML file with a plain-text structure that you can read once decrypted.
: Log into your ZTE gateway interface, navigate to Management/System Tools -> User Config Archive , and export the config.bin file. Decrypt Zte Config.bin
Older ZTE routers (e.g., ZXDSL 831 series, early F660) used a simplistic obfuscation method: XOR encryption with a static 16-byte key. This is not real encryption; it’s a reversible transform. The key was discovered through reverse engineering and is widely published.
Several tools and techniques are available, depending on the complexity of your device's firmware:
Place your config.bin into the utility folder. The encryption key is often derived from the
Several developers have created GUI-based "ZTE Password Decryptors." These are often lightweight Windows applications where you load the .bin file, and the tool automatically searches for and decrypts the administrative and PPPoE passwords.
While decrypting a device you own for personal troubleshooting is a common practice, certain precautions must be kept in mind:
Many modern ZTE routers (especially Type 4 or 6) derive their AES key from hardware identifiers. The Key Formula: Often a combination of the Serial Number (last 8 characters in uppercase) + MAC Address (written in reverse/right-to-left without colons). Command Example: python3 examples/decode.py config.bin config.xml --key 'YOUR_DERIVED_KEY' Use code with caution.
