Karen's Hasher permits computing and verifying 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. And on the flip side, if two strings or files have different hash values, their contents will also be different as well.

Karen's Hasher will permit you to:

-Compute the hash value of a text string
-Compute individual hash values of one or more files
-Compute one hash value for a group of files or folders
-Verify previously saved hash values
