Wanted: 3rd party encryption tools for Windows

As of late, I've got several boxes running Windows(for f@h) and would like to use a 3rd party encryption tool(s) in order to secure personal data. I'd like to use something simple like bcrypt, which is available in Linux; I actually googled for "bcrypt for Windows" but wasn't finding any hits that seemed 'legitimate'.

Just one request- has to be freeware only.

As always, any & all help will be much appreciated.

Truecrypt

I haven't used it personally but I know several people that do and they love it.

+1 for truecrypt.

I use Trucrypt. Extremely easy to use and I've never had a problem with it.

+4 for truecrypt! Very cool, setup an encrypted volume, mounted, added data and umounted.

Thx guys!
