Answer 1

You might want to try HashCheck Shell Extension (Windows only) or HashTab (Windows and Mac). It extends the Windows Explorer file properties dialog, adding another tab containing the file's CRC32, MD5, and SHA1 hashes.

If you're running Linux, see the md5sum and sha1sum commands. You could easily extend your window manager to add a shortcut on the file context window, passing the filename to these commands.
