regards to professional cryptographers, here are two quotes: First, from Matthew Green: > A while ago on Twitter somebody asked why I spend so much time criticizing things that are old and broken, rather than making things new and shiny. When I finished sputtering, I realized that the answer is simple: I'm lazy. (from this blogpost: http://blog.cryptographyengineering.com/2012/12/the-anatomy-of-bad-idea.html http://blog.cryptographyengineering.com/2012/12/the-anatomy-... ) and the second from Diffie & Helman's classic paper, _New Directions in Cryptography_ > The last characteristic which we note in the history of cryptography is the division between amateur and professional cryptographers. Skill in production cryptanalysis has always been heavily on the side of the professionals, but innovation, particularly in the design of new types of cryptographic systems, has come primarily from the amateurs. (from: http://www.cs.jhu.edu/~rubin/courses/sp03/papers/diffie.hellman.pdf http://www.cs.jhu.edu/~rubin/courses/sp03/papers/diffie.hell...) (note that "cryptanalysis" means _breaking cryptographic systems_)
