Configure advanced encryption patterns You can build a pattern using a Java RegEx expression. Before you begin In order to use encryption patterns, you must install and set up a proxy database in your network. This is the same database used for order-preserving encryption. In order to create or edit encryption patterns, you must be connected to the instance through the proxy. Role required: security-admin About this task The input type defines how you are going to enter the pattern. It does not impact how the pattern is used. To enter a series of character types use the basic input type. To enter a Java RegEx expression use the advanced input type. To use one of the preconfigured patterns, edit one of the patterns on the Advanced Patterns list. Procedure Navigate to Edge Encryption Configuration > Encryption Patterns > Create New. Enter the pattern name. In the Edge pattern input type list, select Advanced. When the Convert basic pattern to advanced dialog is shown, click OK. In the Sample match edit box, enter a sample pattern. Use this sample pattern to test the RegEx expression you enter. You cannot save the pattern until the pattern matches the sample. In the Pattern edit box, enter a Java RegEx expression. Click the Validate button to verify that the expression matches the sample pattern. Click Submit.
