ABSTRACT:
A method and system for Certificate management and transfer between messaging clients are disclosed. When communications are established between a first messaging client and a second messaging client, one or more Certificates stored on the first messaging client may be selected and transferred to the second messaging client. Messaging clients may thereby share Certificates. Certificate management functions such as Certificate deletions, Certificate updates and Certificate status checks may also be provided.
