The DataSync Agent can be configured to decrypt ServiceNow records with data encrypted using Edge Encryption. Perspectium provides support for records encrypted using the AES-128 and AES-256 options.
Prerequisites
First, you will need to set up one of the Perspectium DataSync Agents.
You should stop running your DataSync Agent before making any Agent configuration changes.
The DataSync Agent provides a plugin to support decrypting data that is edge encrypted. In order to decrypt this, you will need the following:
- Edge Encryption enabled in your ServiceNow instance
- Edge Encryption proxy server installed and configured
- Keystore containing the encryption key must be saved locally or in an Azure Key Vault
With this information available, add the following configuration directives to your task definition within your agent.xml file:
All attributes are required to access the key vault and open the keystore from the Azure vault.
If the keystore containing the encryption key is saved in an Azure Key Vault, add the following:
