Is there a tool to encrypt a file or directory?


Are there any alternatives to TrueCrypt that work out of the box and don't require any installation? I am looking for something built right into Linux that I use to protect my data. Encrypting the partition is also a good idea.

What should I be looking at?


I don't know of any other encryption programs that will work without a download and installation, you could try LUKS, http://code.google.com/p/cryptsetup/, it is an alternative to Trucrypt that is made to work well with Linux operating systems, but it needs to downloaded and installed, however, you most likely could install it to a small USB flashdrive and always run it from that......
