>I've looked at doing that as part of my X.509 style guide, >http://www.cs.auckland.ac.nz/pgut001/x509guide.txt, This URL isn't quite right, something in this mailer is eating tildes and got the one before the 'p'. The correct URL is http://www.cs.auckland.ac.nz/~pgut001/x509guide.txt (I hope it works this time). Sorry about the confusion. Peter.
