A free, open source program for computing MD5 and SHA hash values on Windows with a simple interface for generating hashes from files or text.
WinMD5Free is a lightweight, free, and open source utility for computing MD5 and SHA hash values on Windows operating systems. Developed by Alexander Yushchenko and first released in 2002, WinMD5Free provides an easy way for users to generate checksums and validate file integrity.
The program has a straightforward graphical user interface that allows selecting files or typing text to hash. It can calculate MD5, SHA-1, SHA-256, and SHA-512 hashes. After computing the cryptographic hash, WinMD5Free displays the checksum values and provides options to copy them to the clipboard.
As an open source tool, the C/C++ source code for WinMD5Free is available for examination and modification. It compiles and runs natively on Windows with no dependencies. Weighing in at just around 100KB, WinMD5Free has a tiny footprint that makes it well-suited for use on USB drives or limited storage.
With its focus on portability and essential checksum features, WinMD5Free serves a niche for Windows users looking for a basic FOSS hash utility. It lacks some advanced capabilities found in larger suites but excels at delivering core functionality in a zero-bloat package.
