shttp for dummies

SHTTP means Secure Hypertext Transfer Protocol which is developed by Enterprise Integration Technologies in 1995 to ensure security with commercial transactions on the Internet. A protocol that provides secure transactions over the Web. It is endorsed by a variety of organizations.
SHTTP encrypts data transfers, but does not authenticate the client. The responsibility for authentication remains with the website (i.e. the responsibility for determining whether the visitor should be shown the information in the first place).
S-HTTP is capable of distinguishing the origin of a particular document on any server, thereby protecting property rights. S-HTTP provides a wide variety of mechanisms to provide for confidentiality, authentication, and integrity.
