HashTools 4.0 + Portable | 2.9/1.3 Mb
HashTools is an application that calculates hashes for given files. It can calculate CRC32, MD5, SHA1, SHA256, SHA384 and SHA512 hashes, and generate an SFV file for your files if needed. HashTools can also add itself to the Windows Explorer context menu for easy. Just select a file to generate a hash for, click on the button for the type of hash to generate and watch the result magically appear. Once a hash is generated you can copy it to the clipboard, or automatically compare hashes to make sure your file is intact.
