Abstract: This present invention provides users with secure transparent electronic communication, allowing them to send and receive encrypted and/or signed messages with little or no user involvement. In various embodiments, the present invention provides a user with e-mail security via automated hierarchical techniques for transparently sending and receiving secure messages, and lowers the burden on administrators. Such a system can also manage cryptographic keys and certificates for the users, and creates such keys and certificates for the users when necessary. A server according to the present invention can intercept unsecured messages from a user, automatically transform those messages into secured messages, and transmit those secure messages to the intended recipients. The server can also automatically transform messages after the recipient sends a digital identity to the server and downloads the software necessary for transforming the secured messages back into readable messages (i.e.

Abstract: The invention includes a computer readable medium storing executable instructions to enroll a user with a secure email support facility. The computer readable medium includes executable instructions to send an enrollment message, supply a registration response, and confirm the registration response. An authentication email is also sent. A client identifies the authentication email. Authentication information within the authentication email is decrypted. The authentication information is used to authenticate the client and subsequently obtain access to a secure email support facility.

Abstract: A hitch assembly including a frame for being attached to a tow vehicle; a cradle assembly pivotally attached to the frame for pivotal fore and aft movement; a hitch receiver mounted to the cradle assembly for being attached to a trailer; a leaf spring mounted to the cradle assembly and the fore end of the frame for controlling fore and aft movement of the cradle assembly; and shock absorbers mounted to the cradle assembly and the aft end of the frame for dampening fore and aft movement of the cradle assembly.

Abstract: This present invention provides users with secure transparent electronic communication, allowing them to send and receive encrypted and/or signed messages with little or no user involvement. In various embodiments, the present invention provides a user with e-mail security via automated hierarchical techniques for transparently sending and receiving secure messages, and lowers the burden on administrators. The present invention can include a server in a local network that acts as a proxy between a user and an open communications network, thereby providing transparent transmission and receipt of secure messages for the user. This could be used for sending and receiving secure e-mail or for securing instant messaging (IM). A server according to the present invention can intercept unsecured messages from a user, automatically transform those messages into secured messages, and transmit those secure messages to the intended recipients.

Abstract: This present invention provides users with secure transparent electronic communication, allowing them to send and receive encrypted and/or signed messages with little or no user involvement. In various embodiments, the present invention provides a user with e-mail security via automated hierarchical techniques for transparently sending and receiving secure messages, lowers the burden on administrators, and allows for a public key infrastructure (PKI) to be dynamically constructed and operated. Such a system can also manage cryptographic keys and certificates for the users, and create such keys and certificates for the users when necessary. The server can also receive an indication that a user has been properly authenticated, check whether the user has a cryptographic key, and automatically create a key if the user does not have one, thereby automatically registering the user within a community and allowing the user to transparently send and receive secure electronic messages.

Abstract: A process for the manufacture of 2,4- and 2,6-diaminotoluenes comprises catalytically hydrogenating the corresponding molten nitro compound in the presence of water, adding hydrochloric acid to form the monohydrochlorides, crystallizing 2,6-diaminotoluene monohydrochloride, filtering it off and, if desired, liberating the free bases by addition of an alkali.
