Cypherpunks, Question concerning MIT PGP 6.2 & PGP 6.2 ui. If it is known that the PGP that encrypted a msg is one of these two versions, then can it be determined which of these two versions did the encrypting? Also, can it be determined that it was not VIACRYPT that did it. Note: If it can be determined that PGP 6.2 ui did it, then it might be a neat trick to change the ui version to mimic either of the other two at user command. Yours Truly, Gary Jeffers
