Managing CDP for Teradata VCL Applications

An application definition contains necessary configurations that are required for a client to function smoothly. A registration token generated while defining the application is used to register the clients with the CipherTrust Manager.

The application definition includes:

• Configuration parameters: required to initialize and configure the client.

• CSR parameters: required to create or renew client certificates and keys.

• CA parameters: required to issue and install digital certificates and CSR.

In this article, you will learn how to:

• Define application

• View application
