I have recently wanted to encrypt entire storage mediums such as external hardrives and flash memory devices. For example it would be ideal to have the option to encrypt the whole filesystem, as well as flash drives. If you have any ideas for the methods and applications that encrypt devices such as flashdrives please list some of them. The particular distro of Linux I am using is Ubuntu 9.10
Im sure the answer to my question will be simple and useful to others. Try to also state in your replies applications that use more advanced encryption algorithms then others, and also it may help to tell us which one you feel is best and why.
