How are Encrypted Msgs extracted in DWA Task?

DWA, cannot display an encrypted message properly until the user’s Id and password are embedded into the Notes Mail file.

Does some one know the task[s] that is/are run that allows Domino to decrypt the message for DWA display.

I have to write an API that mimics that for a mail archiving program.

Thanx.
