Personal security environment for the AS ABAP to use for digital signature functions.
The AS ABAP uses its system PSE to create and verify digital signatures. However, it cannot use the system PSE for encrypting information.
The system PSE contains the system's security information including its public and private key pair and the corresponding certificate list.
The system PSE is created during the system's installation process and stored in the file $(DIR_INSTANCE)/sec/SAPSYS.pse. When creating the system PSE, the system creates a single PSE and distributes it to all of its application servers.
