IgorWare Hasher is a free and portable SHA-1, MD5 and CRC32 hash generator for files and text. It can be used to generate checksums for a single file and save cheksums in verification files (.sha, .md5 and .sfv) or verify its integrity by using verification files generated by Total Commander and FreeComander.
