Configure Edge Encryption on the instance Configure Edge Encryption by configuring fields and attachments for encryption. Before you encrypt a field, determine what system features might be impacted. Examine all scripts for use of the field. Before marking a field as encrypted, make any desired adjustments to the field's size. After a field has been configured for encryption, the field size cannot be changed. Marking a field to be encrypted expands the field size to hold the extra space needed to store the encrypted data. The process of expanding the field size can take a long time depending on how many records the table has. Test all changes on a sub-production instance before making the changes to the production instance. To configure field encryption, you must be connected to the instance through the Edge Encryption proxy. Configure field encryptionSelect the fields to be encrypted and identify the encryption type.
