Using Column Level Encryption Release version: Zurich Updated February 1, 2026 1 minute to readUse Column Level Encryption to manage access to encrypted data on your instances. Use the related links to find information on common Field Encryption tasks. Create cryptographic module for Column Level EncryptionCreate a Column Level Encryption cryptographic module to define the mechanisms used for cryptographic operations.Encrypt data using the Multiple Modules featureEncrypt data with more than one encryption module permitting the user to determine which keys are used for specific rows within the encrypted data.Create a cryptographic specification for Column Level EncryptionAfter you create a cryptographic module, access the corresponding cryptographic specification to define the algorithm.Configure advanced algorithms for Column Level Encryption EnterpriseCreate a cryptographic specification to define the algorithm for a cryptographic module. Customize the encryption specifications with advanced options that are available for Column Level Encryption Enterprise.Using customer supplied keys with Column Level Encryption EnterpriseYou can use your own customer-supplied key instead of using the ServiceNow® system-generated keys.Encrypting fields and attachmentsOnce cryptographic modules are created, a security admin can define the encrypted fields configuration (EFC) and opt to encrypt a field or attachment on a table.Column Level Encryption EnterpriseThese examples walk you through the encryption of fields and attachments using customer-supplied keys.Related conceptsConfigure properties for customer-supplied keysEncrypting fields and attachmentsColumn Level Encryption EnterpriseRelated tasksCreate cryptographic module for Column Level EncryptionCreate a cryptographic specification for Column Level EncryptionConfigure advanced algorithms for Column Level Encryption Enterprise
