IgorWare Hasher is a free SHA-1, MD5 and CRC32 hash generator for Windows, both 64bit and 32bit version is available. As all my programs this one is also portable so there is no installation and does NOT require additional dll libraries or .Net installation.

You can use IgorWare Hasher to generate checksum for single file and verify its integrity by using verification files (.sha, .md5 and .sfv) generated by Total Commander, with support for UTF-8 verification files. Verification files will be loaded automatically if found.

NOTE: 32bit version can work in Windows 98 and Windows Me if you install KernelEx. KernelEx is compatibility layer that allows running Windows 2000/XP applications on Windows 98 and Windows Millennium operating systems.
