MD5 (MD5 message digest utility)

Release date: 
Friday, 21 October, 2016



Authors/Port authors:

The MD5 utility takes as input a message of arbitrary length (e.g. the contents of a file) and produces as output a 128-bit 'fingerprint' or 'message digest' of the input. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.

The MD5 algorithm is intended for digital signature applications, where a large file must be `compressed' in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA. MD5 digests are often provided with large files for downloading, the idea being that the downloader is told the MD5 digest for the file, and can thus check that it has been downloaded correctly by running MD5 over the file and comparing the digest with the one provided.

The package includes:

  • The MD5.EXE program
  • The associated README.TXT file
  • Source code
This software is distributed as compressed package. You have to download and manually install it; if prerequisites are required, you will have to manually install them too.
