HTTPS connections are secure connections between a browser and Teradata Database. To enable HTTPS connections, the external server using the browser needs an identifying certificate that provides the public key used to decrypt the information it sends. This certificate may be either self-signed or signed by a Certificate Authority (CA)
To install a new certificate from a CA, generate a Certificate Signing Request and submit it to a CA for signing. After you receive the signed certificate from the CA you can install it.
