Update on Bellcore's Trusted Software Integrity System
------------------------------------------------------


The format of Betsi certificates has now been upgraded
to accomodate multiple files. The md5sum program, which
is included in the contrib directory of the pgp 2.6.1 
distribution, takes a list of files or wildcards as
arguments and produces a list of md5 hash sums followed
by file names. The format of a request for certificate
message is the same as before for one file, and as
follows for multiple files:

The paper at thumper.bellcore.com in /pub/certify/Betsi.ps has been
updated to reflect this upgrade, and it is further explained there.

I am currently working on writing mosaic pages to facilitate the
process of sending various messages to Betsi.

For more information on Betsi send a message to certify@bellcore.com 
with the subject: help.
