Hash Tools is a free utility to calculate a hash from a given text or Decrypt(PRO) a hash to Original text. In this application, the available hash functions are : MD4, MD5, SHA-1, SHA-256, SHA-384, SHA-512, NTLM. Hash functions are often used in cryptography to generate strong passwords.

Hash Tools has been developed in the hope that it will be useful for administrators, security consultants, professional penetration tester and everyone else that plans to use it for ethical reasons. The author will not help or support any illegal activity done with this program.

A hash (also called checksum or digest) is a digital fingerprint, uniquely identifying a string or a file.

Hash functions are often used in cryptography to generate strong passwords. They are also employed to check the integrity of files.
