Used to detect file tampering and duplication Cobynsoft's Hash Calculator is a freeware utility for calculating MD5 and SHA-1 cryptographic hash values for single files or for multiple files by selecting entire folders. The tool will output the file(s) cryptographic hash message digest in form of a hexadecimal string that can be used to verify the integrity of the files.

Supported Cryptographic Hash Algorithms
1. MD5 Message-Digest Algorithm (RFC 1321)
2. SHA-1 Secure Hash Algorithm (RFC 3174)

Grouping
The result can be grouped by any column. For example, by grouping files by their Hash Value you can easily detect duplicate files.

Export your results to a variety of industry standard formats such as
1. Microsoft Excel 2003, XLS
2. Microsoft Excel 2007, XLSX
3. Adobe Portable Document Format, PDF
