digestIT 2004 allows you to easily calculate or verify the MD5 or SHA-1 hash signature for a selected file by simply right-clicking on it and selecting the digestIt option from the menu. You can calculate the hash for multiple files and optionally save the results to a file or copy them to the clipboard. To verify a file against a signature, you can paste it into the box and the program will check if it matches. MD5 and SHA-1 hashes allow to to determine whether a file has been tampered with since the original hash sum was created.
