Abstract
A method and apparatus is provided for effecting secure document delivery in any of various document formats. A document is encrypted with the public key of a server associated with the recipient of the document, instead of with the public key of the intended recipient. The receiving server is located within a firewall. The encrypted document is forwarded to the server within the firewall. The server decrypts the document using its corresponding private key, converts the document to a now data representation, and then either forwards the document to the recipient inside the firewall, or re-encrypts the document with the public key of an intended recipient outside of the firewall or with the public key of another server that is associated with the intended recipient of the document.
