First Claim
1. A method of searching and retrieving certificates relating to a message received from a sender, the message comprising data identifying a sender certificate associated therewith, wherein the method comprises:
- generating certificate identification data for the sender certificate from the data in the received message identifying the sender certificate, wherein the certificate identification data uniquely identifies the sender certificate;
receiving certificate identification data at a computing device; and
determining whether the sender certificate is stored on the computing device, by generating certificate identification data associated with each of a plurality of certificates stored on the computing device, and comparing generated certificate identification data for each of the plurality of stored certificates to the certificate identification data generated for the sender certificate to identify a stored certificate matching the sender certificate.

Abstract
A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one broad aspect, certificate identification data that uniquely identifies a certificate associated with a message is generated. The certificate identification data can then be used to determine whether the certificate is stored on a computing device. Only the certificate identification data is needed to facilitate the determination alleviating the need for a user to download the entire message to the computing device in order to make the determination.
