Open your command prompt or terminal and navigate to that directory. Run the decryption command (syntax varies by script): python zte_config_tool.py -d config.bin config.xml Use code with caution.

For network administrators, cybersecurity researchers, and advanced home users, the humble router is both a gateway and a vault. Within its flash memory lies the key to the entire network: administrator passwords, PPPoE credentials, Wi-Fi PSKs, and often custom firewall rules. ZTE, a major global telecommunications equipment manufacturer, protects these secrets by storing them in an encrypted file typically named config.bin . When users back up their router settings, they are handed this binary blob—a seemingly unintelligible wall of data. Decrypt Zte Config.bin
The key may be specific to your router model. You may need to extract the key from the router's firmware.
If your goal is to change advanced settings (e.g., unlocking hidden VoIP settings or changing restricted DNS configurations), you can modify the decrypted XML file and pack it back into a .bin format.
ZTE routers use different methods to secure their configuration files, often referred to as "payload types": ZTE F6601P - Encode to config.bin file using ... - GitHub mkst/zte-config-utility: Scripts for decoding/encoding
Ensure Python 3 is installed on your computer. Open your terminal or command prompt and install the required cryptographic libraries: pip install pycryptodome Use code with caution. Step 2: Download the Decryption Tool
Before attempting any method, log into your ZTE router gateway (usually 192.168.1.1 or 192.168.0.1 ), navigate to , and select Backup Configuration to download your config.bin file. Method 1: Using the RouterPassView Utility (Easiest)
If the output file is not plain text, it is likely still compressed with zlib. Run a zlib decompression script or use an online extraction tool to reveal the final XML structure. Common Router Key Database # After AES decrypt, you might have a
If the file format is supported, the tool will instantly decrypt it and display a clean list of recovered usernames, ISP passwords, and wireless keys. Method 3: Manual Decryption via Known AES Keys
Do not attempt to open the config.bin file in a standard text editor like Notepad, as it will display corrupted binary data. Instead, gather the following tools:
Use Binwalk in a Linux environment to analyze and extract the firmware components: binwalk -e firmware.bin Use code with caution.
Then, you can look for the decrypted file in /tmp/debug-decry-cfg and copy it to your PC. Summary Table: Common Decryption Keys
Depending on the specific router model and firmware version, one of the following methods is typically used:
