Foil 109 SSL from Netscape I

From Remarks on Internet and Java Security Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Mehmet Sen


1 SSL provides a security "handshake" (certificates and public keys) that is used to initiate the TCP/IP connection. This handshake results in the client and server agreeing on the level of security they will use and fulfills any authentication requirements for the connection.
2 Thereafter, SSL's only role is to encrypt and decrypt the bytestream of the application protocol being used (for example, HTTP, NNTP, or Telnet). This means that all the information in both the HTTP request and the HTTP response are fully encrypted, including the URL the client is requesting, any submitted form contents (including things like credit card numbers), and HTTP access authorization information (usernames and passwords), and all the data returned from the server to the client.
3 Netscape Navigator includes embedded Certificate Authority (CA) keys for certain CAs, including our test CAs.
  • As new CAs come online, we will embed their keys as well.
