Summary: New trusted certificate from Verisign
Verisign has distributed a new trusted CA certificate.
The Verisign CA certificate used to sign the server certs used for
rule delivery will expire in December 2006 (one year away). This
trusted.cert file will ensure a smooth transition between the existing
cert and the new cert (which will be valid until 2020).
