Alternate HASH-Generator is a freeware app that allows you to quickly generate HASH values or checksums out of a string or a file.
It supports 21 hash algorithms that can be easily chosen from a drop-down box depending on your specific needs.
Another useful tool included with Alternate HASH-Generator is the expected value field; this is used for checking the state of a target file at different times to make sure no changes have been made at any time. The limitation here is that it will only inform you if the hash codes match or not - no other specifics are given.
Alternate HASH-Generator proves to be a useful tool for providing immediate first-line information regarding the integrity of a file that may be in question.
