Using Individual Encryption Keys
The secure storage in the file system stores encryption keys for the secure storage (ABAP). There can be more than one encryption key for the secure storage (ABAP) in the secure storage in the file system. One of the keys can be the current key, which means that it is currently being used for records you want to encrypt. The remaining keys decrypt records that have been inserted with the respective key as encryption key.
You can protect those records that have been encrypted with encryption keys other than the current key by re-encrypting them to the current key.
In the following figure, you see the keys of the secure storage in the file system that are used by the secure storage (ABAP). The key identifier 4713 is the current key, which is currently being used for encryption. The system uses the remaining key identifiers to decrypt entries that are associated with those keys.
