: While older models sometimes used hardcoded keys, modern versions derive keys dynamically from device-specific identifiers like the Serial Number , MAC Address , or even unique salts stored in internal router databases.
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.

: If the specific key is unknown, try python3 examples/decode.py config.bin config.xml --try-all-known-keys . Alternative: On-Device Decryption : While older models sometimes used hardcoded keys,
