"There are two kinds of cryptography in this world: cryptography that will stop your kid sister from reading your files, and cryptography that will stop major governments from reading your files."

— Bruce Schneier

"There are three (3) kinds of cryptography in this world: cryptography that will stop your kid sister from reading your files, cryptography that will stop major governments from reading your files, and finally, the strongest cryptography -- cryptography that will stop Bruce Schneier -- from reading your files." <g>

(Bruce Schneier = Cryptography's Chuck Norris...<g>)

((And the third such cryptography, if it exists... will be found to have been created by -- you guessed it -- Bruce Schneier! <g>))
