Hasher - Hash Generator

IgorWare Hasher is a free, portable hash generator for Windows that allows users to create and verify file checksums using common hashing algorithms such as SHA-1, MD5, and CRC32. This lightweight checksum calculator is designed for quick file integrity checks and supports automatic verification using checksum files, making it useful for validating downloads and detecting file corruption.

MD5 Checksum Calculator

MD5 Checksum Calculator previously called (RiMD5), is a tiny portable freeware utility that can be used to generate, calculate, compare and validate checksum values or MD5 (Message Digest number 5) of specified files. This checksum generator takes the input message of the chosen file and creates a resulting 128 bit fingerprint for the file. It is nearly impossible to produce two messages having the exact same message digest, hash or checksum.
