Abstract
Briefly, in accordance with one or more embodiments, a transport level transactional security may be converted into a persistent document signature. In one embodiment, a digital signature of an electronic mail message may be saved in a file attached to the electronic mail message. The file with the added digital signature may be saved, transmitted, received, and/or otherwise utilized independent of the original electronic mail message. A receiving node may verify the identity of an originating node based at least in part on the digital signature contained in the file. In alternative embodiment, the signature for the file may be generated at least in part on a message to be transmitted according to a secure transmission and/or file download protocol from a server to a client.
