JotTek provides Secure Hash Algorithim 256 (SHA256) Checksums for manuals, drivers and firmware upgrades to ensure that the version you have is not tampered with or corrupt.

The fastest way to identify the SHA256 checksum of a file is by installing a file management program like 7-Zip. Additionally, you can use the Command Prompt on Windows 7 or newer.

You can then compare the checksum listed onto JotTek to determine the integrity of your version. Every checksum listed onto JotTek is downloaded and verified from the manufacturer.
