# Encode the modified config.xml back to config.bin python3 examples/encode.py config.xml config-novo.bin --key YOUR_KEY --iv YOUR_IV --signature YOUR_MODEL --include-header
: Once decrypted, the data is usually found in compressed ZLIB blocks.
Make your precise edits inside the config.xml file. Save the changes.
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. Decrypt Zte Config.bin
Open a terminal in the utility folder and try the following methods in order:
Then, you can look for the decrypted file in /tmp/debug-decry-cfg and copy it to your PC. Summary Table: Common Decryption Keys
python3 examples/encode.py modified_config.xml output_config.bin --key "YOUR_KEY" --signature "DEVICE_SIG" --payload-type 4 # Encode the modified config
For AES‑encrypted config.bin (detect via entropy or lack of plaintext header after XOR):
[ Raw XML Configuration Data ] ↓ ( zlib Compression ) ↓ ( AES Encryption Layer / Obfuscation ) ↓ [ Encrypted config.bin File ]
If your config.bin starts with SEND or ZTE in hex ( 53 45 4E 44 ), it’s likely XOR-obfuscated: When you back up a ZTE router's configuration
(Alternatively, you can clone repository forks like zte_config_exporter directly from GitHub.) Step 2: Run the Decryption Command
If you are dealing with an older ZTE router model (such as the ZXHN H108N or similar legacy devices), NirSoft’s is a lightweight, GUI-based Windows application that can parse the file instantly. Download RouterPassView from the official NirSoft website. Launch the application.
: If auto-decode fails, you may need to provide specific device details: Serial Number : Often the ONT serial (e.g., ZTEGXXXXXXXX MAC Address : Use the format --mac 'AA:BB:CC:DD:EE:FF' Custom Keys : Some models use specific hardcoded keys (e.g., Renjx%2$CjM Advanced Decryption Methods
