Integrity Checker checks the integrity of your files to ensure they have not been tampered with. The files you select for protection will have their file size stored together with either a hash or HMAC (user selectable) generated from the contents of each file. By comparing this information with what is actually stored on your drives later, any changes will be flagged up for your attention. With some command line parameters, you can load and cross-check the list of files in the background and only be alerted if any integrity mismatch is detected.
