Certificates Authentication with SSL is achieved with a Digital Certificate issued and signed by a Certificate Authority CA and stored on the server Without a certificate signed by a CA the server cannot be reliably identified to the client yet a connection can still proceed if allowed The Digital Certificate resides on a secure server and is used to encrypt data and identify the Web site The Digital Certificate verifies that a site belongs to who it claims to belong to and contains information about the certificate holder the domain that the certificate was issued to the name of the Certificate Authority who issued the certificate the root and the country it was issued in In addition to proving the veracity of a site the Digital Certificate provides the receiver with a way to encode a reply Digital Certificates come in 40 bit and 128 bit versions There are two principal ways to obtain a Digital Certificate It can be bought from a certificate vendor or a user can self sign his or her own certificate With the latter method a user can use various tools both open source and proprietary to sign his or her own Digital Certificate saving the time and expense of going through a certificate vendor EDS Device Servers User Guide 160 C Networking and Security Tunneling Tunneling provides a way to create a connection between two serial devices across an untrusted network so the devices can share data The sharing of information
