Though, technically, no disk can be securely erased, my program, Read Peter Gutmann's paper on securely deleting files at: http://www.cs.auckland.ac.nz/~pgut001/secure_del.html.

Very Good Privacy, can securely delete files after they have been encrypted.

Thought you said "no disk...". So how does VGP do it? I should have added quotes around "securely delete." The end of Peter Gutmann's paper states "it is effectively impossible to sanitise storage locations by simple overwriting them, no matter how many overwrite passes are made or what data patterns are written. However by using the relatively simple methods presented in this paper the task of an attacker can be made significantly more difficult, if not prohibitively expensive." VGP tries to make is prohibitively expensive (that is, in essence, what all ciphers do; someone can break just about any cipher if they have enough money).
