Many ZTE routers and ONTs (e.g., F660, F680, F609, F670L) store their configuration backup in a file named config.bin.
This file is not a plaintext backup – it is encrypted (or obfuscated) to prevent casual modification.
Decryption is often required to:
Common key derivation:
Run the Decryption Script: Open a terminal (CMD or PowerShell) in the utility folder and execute the auto-decoder: python3 examples/auto.py config.bin config.xml Use code with caution. Decrypt Zte Config.bin
Brute-Force Option: If the specific key is unknown, try python3 examples/decode.py config.bin config.xml --try-all-known-keys. Alternative: On-Device Decryption Decrypt Zte Config
Decrypting a ZTE config.bin file typically involves using specialized scripts to reverse the proprietary encryption (often AES-CBC or ZLIB-based obfuscation) applied by the router firmware.
