Secure Storage in the File System (AS ABAP)
The secure storage in the file system is part of SAP NetWeaver Application Server (AS) ABAP. SAP Installer, AS ABAP kernel, and AS ABAP tools can use this storage to securely store connection-relevant data like passwords. The encrypted storage of the data prevents unauthorized persons or programs being able to access this data.
Custom applications cannot use this component.
Files
The secure storage uses the following files:
-
Data file SSFS_ <SAPSYSTEMNAME>.DAT, which is stored in the directory set as the value of profile parameter rsec/ssfs_datapath
-
Data backup file SSFS_ <SAPSYSTEMNAME>.DA_, which is stored in the same directory as the data file. The secure storage creates it before starting an operation that changes the data file in a non-trivial way (see Restoring Secure Storage Files in the File System)
-
Lock file SSFS_ <SAPSYSTEMNAME>.LCK, which is stored in the directory set as the value of profile parameter rsec/ssfs_datapath
-
Key file SSFS_ <SAPSYSTEMNAME>.KEY, which is stored in the directory set as the value of profile parameter rsec/ssfs_keypath
-
Key backup file SSFS_ <SAPSYSTEMNAME>.KE_, which is stored in the same directory as the key file. The secure storage creates it before starting an operation that changes the key file in a non-trivial way (see Restoring Secure Storage Files in the File System)
The files do not need to exist immediately after the installation. The secure storage automatically creates them during the first operation that requires the relevant files to exist.
The secure storage is part of the AS ABAP. You do not need to install any additional libraries or external products.
