WinMd5Sum Portable
Due to some weaknesses in the MD5 hash function, it is better to use SHA-1 checksum keys.
Announce All modern GNU/Linux systems are featuring a sha1sum tool, similar to the md5sum too, so this there should be no problem checking the checksums on these platforms.
For MS Windows no such tool is available.
To solve this problem, I wrote a simple sha1sum tool and uploaded it along with a MS Windows binary (sha1sum.exe) to the GnuPG ftp servers. The source is also available and maybe used to check the correctness or to build own binaries. It should build on all platforms.
Download the sha1sum.exe and put it in your windows system 32 directory (e.g. C:\WINDOWS\system32) directory. You can calculate the checksums key by type sha1sum *.iso on the command prompt. E. g.:
D:\LinuxISO>sha1sum *.iso

The CryptoSys PKI Toolkit (trial, 60 days) provides you with an interface to public key cryptography functions from Visual Basic, VB6, VBA, VB.NET, VB2005, C/C++ and C# programs on any Win32-compatible system (W95/98/Me/NT4/2K/XP/2003/Vista).

The HashCheck Shell Extension makes it easy for you to calculate and verify checksums (including hashes) from Windows Explorer.
First, HashCheck can process and verify the checksums/hashes stored in checksum files--these are files with a .sfv, .md4, .md5 or .sha1 file extension. Just double-click on the checksum file, and HashCheck will check the actual checksums of the listed files against those specified in the checksum file.
Single setup package for both 32-bit and x64 Windows
