What is not so well known about him was that he dabbled in cryptography, and broke the Vigenère cipher; unfortunately for him it was classified as a military secret, so one Friedrich Kasiski got the credit instead. -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer." ^ permalink raw reply [flat|nested] 5+ messages in thread
