WinMD5Free v1.20

As an Internet standard (RFC 1321), MD5 has been used in a wide variety of security applications, and is also commonly used to check the integrity of file, and verify download. WinMD5 is a small and easy tool to calculate md5 hash or checksum for different files (including files larger than 4 GB).

Features:

• Supports almost all Windows platforms including Microsoft Windows 95, 98, 2000, Me, XP, 2003, Vista and 7.
• Fast and multi-threaded. It can compute a 2 GB file less than 1 minute.
• Supports big files larger than 4 GB.
• Low resource usage. It uses less than 5 MB RAM.
• Don’t require .NET runtime installed. It is a standalone EXE file and the startup is speedy. There are MD5 tools for Windows on the market, but most of them requires .NET runtime and they may take a few seconds to start. This is also the reason I wrote the program.
• Supports “Drag & Drop”. You may either select a file, or drag and drop a file to the program window to get the MD5 hash value.
• Supports verification of original MD5 value and current MD5 value.
• Most important, it is FREE. No spyware or adware bundle.
• Small size, an effective and tiny tool for data security.
