As I head out next week to the RSA Conference I realized that it has been 13 years since I attended the first one. I remember fondly the potential and power of cryptography technology in 1991 -- public keys, digital certificates, new possibilities for privacy, digital cash, etc. After 8 more years I left the compujter security industry on March 15, 1999. The computer security industry also seemed to be filled with as much potential as it did back in 1991.
