HashTools

Calculates hashes for MD5, SHA-1, etc. from file input

Cryptographic hashes on the Internet are primarily used for the verification of passwords and downloadad files. HashTools is a command-line toolkit that can quickly calculate MD5, SHA-1/-256/-384/-512, and RIPEMD-160 hashes for files and output the hash to a console. These utilities have been tested against hashes generated by the highly popular OpenSSL cryptographic toolkit.

The tools are written using the .NET Framework 2.0. Vista has this preinstalled. If you're on an earlier operating system and don't already have it installed, you can grab the installer from the Microsoft Download Center.

Syntax

To generate a hash for a file, call the appropriate executable followed by the filename. The following examples produce MD5 and SHA-1 hashes for file.txt and output the hash to the console, where it can be copied/pasted.

MD5 file.txt
SHA-1 file.txt
