SSL/TLS certificates - viewLinc 5.2

viewLinc Enterprise Server (ES) software requires an end-to-end secure HTTPS connection to encrypt and protect data transmitted to logged in users.

During installation, you can upload your company’s existing security certificate and key files, upload a trusted CA-signed certificate, or generate viewLinc-signed certificate and security key files.

Both viewLinc-signed and trusted certificates provide the same level of security between a web browser and the viewLinc Web Server. Table 1 outlines the key features of these certificate options.

If you plan to purchase trusted certificate files, choose the option to generate viewLinc-signed files during viewLinc ES installation. This will generate a .csr file which is required for the purchase of a trusted certificate.
Ensure the list of hostnames and aliases you provide is correct and complete, or users will not be able to connect to the viewLinc webserver. Do not use wildcard domains.
