IgorWare Hasher is a free SHA-1, MD5 and CRC32 hash-generator for Windows and is available in 32- and 64-bit versions. This program is portable and does not require either additional dll libraries or .Net installation. IgorWare Hasher can generate checksums for a 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. It can also generate the checksums for a text string.
