To decrypt the `sensor_data`, 2 keys are required. The keys are extracted from the `bm_sz` cookie. The first one is used to encrypt and the second one is used to change the orders. You simply provide the `bm_sz` cookie and the application will extract the keys within it. 3 | 4 | You can provide the keys too within the `sensor.txt` file in two ways so you will not ever need to execute application with arguments: 5 | 1. `sensor_data` at first line, then `bm_sz` cookie value as the second line! or even the 6 | 2. `sensor_data` at first line, then `first encryption key` as the second line and `second encryption key` as the third line! 7 | 8 | Use `--help` to get the usage. 9 | 10 | ### Found an Issue? 11 | 12 | If you find a bug in the source code or a mistake in the documentation, you can help by submitting an issue to the [GitHub Repository](https://github.com/NotAnAPI/SensorData.Decryptor "GitHub Repository"). Even better you can submit a Pull Request with a fix. 13 | 14 | When submitting an issue please include the following information: 15 | - A description of the issue 16 | - The exception message and stacktrace if an error was thrown 17 | - If possible, please include code that reproduces the issue. DropBox or GitHub's Gist can be used to share large code samples, or you could submit a pull request with the issue reproduced in a new test. 18 | 19 | 20 | The more information you include about the issue, the more likely it is to be fixed! 21 | 22 | ### Submitting a Pull Request 23 | 24 | When submitting a pull request to the [GitHub Repository](https://github.com/NotAnAPI/SensorData.Decryptor "GitHub Repository") make sure to do the following: 25 | 26 | - Check that new and updated code follows Decryptor's existing code formatting and naming standard 27 | 28 | ### Discord 29 | [Join the Discord server](https://discord.com/invite/MkzEUqEAbD "Join the Discord server") 30 | --------------------------------------------------------------------------------
