ARIN is in the process of transitioning many of our current services to 
the new web-based ARIN Online platform.  Because the web-based platform 
will use a more secure authentication model, ARIN will be deprecating 
support for X.509 certificates. After 28 May 2010, ARIN will not accept 
new requests for X.509 certificates. ARIN will continue supporting the 
use of X.509 certificates for user authentication until late 2010. After 
that time, all transactions with X.509 signatures will no longer be 
authenticated. We encourage people who are using X.509 to either move to 
PGP (Pretty Good Privacy) or to use ARIN Online as new features become 

If you have any questions, comments, or concerns, please do not hesitate 
to contact us at hostmaster at arin.net.
