Tom’s Hash Explorer is a free Windows utility that allows you to easily calculate cryptographic hash values for single or multiple files in order to verify file integrity.

Tom’s Hash Explorer features an innovative Explorer-like graphical user interface to navigate your file system and calculate cryptographic hash values for either a single file or for all files within a folder. The most popular Hash algorithms are supported, including MD5 Message-Digest Algorithm, SHA1 (160-bits), and SHA2 (256 bits, 384-bits, and 512 bits). Its multi-threaded hash computation engine results in extremely fast results.
