Both Netscape Navigator and Microsoft’s Internet Explorer contain extensive support for SSL. This section describes the support for transferring documents using encryption. SSL’s support for digital certificates is described in the next section.
Netscape Navigator uses the term “secure document” as a shorthand for the phrase “documents that are transmitted using SSL.”
Of course, documents transmitted using SSL aren’t any more secure or unsecure than documents that are sent in the clear. They are simply cryptographicallly protected against eavesdropping and modification while in transit.
Netscape Navigator 3.0 and Internet Explorer 3.0 control their SSL behavior through the use of special panels.
