Hash Tool is a utility to calculate the hash of multiple files. A file hash can be said to be the ‘signature’ of a file and is used in many applications, including checking the integrity of downloaded files. This compact application helps you quickly and easily list the hashes of your files. You can also create hashes for lists of text strings. Hashes supported include MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32.
