Definition
The application server's PSE for securing communications using Secure Network Communications (SNC) when you use the SAP Cryptographic Library as the security product.
Use SNC to protect connections where the SAP protocols are used, for example, RFC and DIAG. (Note however, you cannot use the SAP Cryptographic Library on client components such as SAP GUI for Windows.)
Use SSL to protect HTTP connections.
Structure
The SNC PSE contains the server's security information to use for securing the SNC connection. This information includes the server's public and private key and the corresponding certificate list.
Integration
When you create the SNC PSE, the system generates a single PSE for the system that is distributed to all of the application servers. The system stores the PSE in the file
$(DIR_INSTANCE)/sec/SAPSNCS.pse.
