There are several free downloadable tools and utilities that can be used to retrieve or get the hash or checksum value value (also known as message digest or digital fingerprint) of a file or software installer by computing or calculating the cryptographic hash function algorithms.

How to Determine, Calculate or Computer the Hash or Checksum of a File on Your Local PC Hash function adds additional security properties to the file so that any unauthorized modified and altered file will not have the same digital hash fingerprint. Two most commonly used hashes are MD5 and SHA1. To protect a file and ensure that the program is correct, perform only what is advertised and nothing more, stable, well-written, and is actually the original or the same file that been put up for download by the author, we can compare the cryptographic hash function of the downloaded file with the hash value or checksum that been posted or declared by the developer for the file, software or application (other verification method been the installer been signed with digital certificate, which used by large corporations only due to cost). If you download a file from the Internet, you take some risks that the file you downloaded is compromised or been altered or corrupted illegally by ill-intent cracker or hacker.
