The encrypted storage of the data in the database prevents unauthorized persons or programs being able to access this data.
The data transferred to the secure storage by the application is encrypted and stored in the database. When you access the data, it is decrypted again.
The encryption key resides in the file system of the application server(s) and is maintained by a key management procedure.
Before the key management procedure is carried out for the first time, the secure storage encrypts data using a default key which provides obfuscation only.
You can review the key status in the SECSTORE transaction.
The secure storage is a component of the SAP NetWeaver Application Server for ABAP. You do not need to install any additional libraries or external products.
For legal reasons, only SAP applications may use the secure storage. We therefore use technical measures to prevent the secure storage being used in customer developments.
SAP provides the Secure Store & Forward interface for external products for your own developments.
