X.509 guide/notes available

[<pgut001@xxxxxxxxxxxxxxxxx>]

I've now made the X.509 notes I posted here some time ago available online at
http://www.cs.auckland.ac.nz/~pgut001/x509guide.txt.  They carry the rather 
pretentious title "X.509 Style Guide" because they started out as an attempt 
to clarify some rather unclear X.509 implementation issues and provide hints 
on potential problem spots.  Here's the introduction:
 
>There seems to be a lot of confusion out there about how to implement and work
>with X.509 certificates, mainly due to either ASN.1 encoding issues, or becaus
>the general non-presence of X.500 means people have to take guesses at what
>some of the X.500-related fields are supposed to look like.  For this reason I
>decided to put together some guidelines which people could follow when creatin
>software to work with X.509 certificates, CRL's, and other ASN.1-encoded data
>types. The document is intended to be a collection of the experiences of
>developers and implementors to help developers new to the area create
>interoperable implementations.
 
Before people point this out, I've just noticed that the comments about Y2K 
problems are out of date, I'll change that section of the text within the next 
few days.
