To create a Connector, you must first store the authorization information in an Authorization Vault, which provides a secure storage location for API keys, tokens, username and passwords, headers, and other info used to authorize calls to external Web Services. In order for a Cloud Connector to work, this vault entry must exist and be configured for the external application you wish to communicate with.
Security - protection of vault data
When Clarify is installed, a random seed is generated for the encryption algorithm used for storing data in the database. This way each customer's data is uniquely encrypted. Someone can not simply select data from the table and understand the content, they would also need that key and knowledge of the algorithm used.
The vault entry can be created from the Admin Console’s Settings | Auth Vault view, or directly from the Cloud Connector wizard (shown below). See Configuring servers for Local or Remote Vault connections to learn how to create a vault entry.
