From the developer:
Compute and verify the MD5, SHA-1, SHA-224, SHA-256, SHA-384 or SHA-512 Hash Value of any text string, disk file, or group of files. A Hash Value is a sort of digital fingerprint, uniquely identifying each text string or file. If two strings or files have the same Hash Value, then they are virtually guaranteed to be identical.
