FlyingBit Hash Calculator integrates with the Windows Explorer and enables you to calculate and verify hash sums for any file from the right-click menu. It supports 9 different algorithms including MD5, CRC32, SHA1 and TIGER. All sums are generated at the same time and you can choose which one to copy to the clipboard, or save them all as a .hash file. The program can also create a GNU .md5 check file containing the .md5 signature of a file and later compare it to the original.
