Method and apparatus for digitally signing electronic mail that originates from a browser

摘要

One embodiment of the present invention provides a system for digitally signing electronic mail that originates from a browser. The system operates by first receiving a message from a browser at a mail server. The mail server formats the message and returns the formatted message to the browser so that the browser can sign the message. The mail server then receives the signature for the formatted message from the browser and encapsulates the formatted message and the signature into a secure message. Next, the mail server forwards the secure message to the intended recipients for the message.
