<strong>Peter Gutmann</strong> is a researcher in the Department of Computer Science at the University of Auckland working on design and analysis of cryptographic security architectures. He helped write the popular PGP encryption package, has authored a number of papers and RFC's on security and encryption, and is the author of the open source cryptlib security toolkit. In his spare time he pokes holes in whatever security systems and mechanisms catch his attention and grumbles about the lack of consideration of human factors in designing security systems.
