As some may have noticed, I don't type particularly well or fast (I thought), using two fingers and a thumb. However, several times, when experimenting with PGP2.1 key construction, I have received screen messages requiring me to add to the character stream as some earlier characters had been typed in too fast. I understand this to mean that the time interval from one character to the next was too small for the key generation program (under DOS) to use. Though noting the occurences, until Rob's post, I did not give them much further thought. Does anyone know what the limits on the time interval measurement are and what effect this will have on the random number vectors? Owen ___ Blue Wave/QWK v2.11
