AES-128-CBC payload decryption is now supported for KnightX 100 devices. Encrypted location and alarm packets are decrypted and parsed into full telemetry (position, speed, battery, alarms, acceleration, mileage).
To use it, set the device's encryption.key configuration field to the MD5 hash (32 hex characters) of the key you programmed on the device with SETKEY. The fixed IV is handled automatically. Devices without an encryption key configured continue to send and parse unencrypted traffic as before.
