What do I need to use to encrypt my USB hard disk?

How to encrypt an USB stick?

I want to encrypt my USB hard disk. And I want to do it with open source software. And I want to use only password for decryption. And I want to decrypt it using an Ubuntu 10.04 LiveCD, with no Internet-connection. And I don't want solutions using, for example, DES with 56 bit. At least AES 256 bit, please!

What is the solution?

You want to use LUKS for that. Steps 5 through 7 are the important ones.

You can have the program on the HDD (obviously not encrypting that part of the drive.) – None – 2010-10-23T23:13:31.597

"i want to decrypt it using an Ubuntu 10.04 LiveCD, with no internet-connection." -> plus....i can't even download truecrypt, because the tar.gz file, that contains the sources is corrupt, at least when i want to download it from truecrypt.org..... -> but thank you! – None – 2010-10-23T23:15:26.233
