Decrypt Zte Config.bin Site

After decryption, the file ends with a 4-byte CRC32 of the original ciphertext. Tools often ignore this for extraction but recalc it for repacking.

key = b"Zte521@!Zte521@!Zte521@!Zte521@!" with open("config.bin", "rb") as f: data = f.read() plain = bytearray() for i, byte in enumerate(data): plain.append(byte ^ key[i % len(key)]) # plain now contains the XML config Decrypt Zte Config.bin

The tool reads the file, XORs each byte sequentially with the repeating key, and writes the output. The result is almost always a plaintext XML file (declaration: <?xml version="1.0"?> ). After decryption, the file ends with a 4-byte
