The > byte is not really specuial. And let's not forget that at the time when many long-lasting encryption algorithms (DES, RSA, anyone?) were being designed, it still wasn't an open-and-shut case whether even a digital binary computer would represent data in 8-bit chunks or not. Octal was still big in the late 1970s. -- Michael Kjörling • https://michael.kjorling.se • michael@kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
