>HashTab is a freeware Windows shell extension which adds a tab called “File Hashes” to the Windows Explorer file properties. The tab displays the MD5, SHA1 and CRC-32 hashes for the viewed file.
MD5, SHA1 and CRC-32 are common hashes that are displayed on the website of the software author to verify the integrity and authenticity of files after downloading.
