Free Encryption software to use

[prost]

ccrypt-1.9.tar.gz from http://www.mathstat.dal.ca/~selinger/ccrypt/ 650Kb works well and is very user friendly. There is a version for Windows 95-XP. You should also get ccrypt_gui_integration.zip 20Kb from http://ccrypt.sourceforge.net/VF/README.html which allows you to encrypt/decrypt files/folders by right-clicking on them in Linux KDE, Gnome, and Windows 98+. I think that in Windows you double click 'ccrypt-Win32-install.bat' to install it.

ccrypt is based on the Rijndael block cipher, with 256-bit block size and 256-bit key size. The Rijndael cipher is the U.S. government's chosen candidate for the Advanced Encryption Standard.

The good thing about it is that after encrypting files, you don't have to delete the original file. I'm using it in Linux and will need to send encrypted files to Windows users, so I wondered if ccrypt-1.9 works in Windows vista and 7. Can people let me know?

There is a version for mac if you use google.

[Linux users: There is a ccrypt for Ubuntu/debian users.

To install ccrypt_gui_integration.zip, uncompress it. Open a terminal. Then type in the full path name. Like '/home/yourusername/ccrypt-kde-install' if it was in your home folder. It works for KDE 3.5 but I'm not sure about KDE 4.]
