Procedure documentationInstalling the SAP Cryptographic Library on the SAP Web Dispatcher Locate this document in the navigation structure

 

If the SAP Web Dispatcher is to terminate or re-encrypt the connection request, it must use the SAP Cryptographic Library to perform the SSL encryption functions. Use the following procedure to install the library on the SAP Web Dispatcher.

Note Note

If the SAP Web Dispatcher passes the SSL connection to the back-end application server, it does need to possess its own security environment and you can skip these steps.

End of the note.

Prerequisites

You have obtained the SAP Cryptographic Library installation package.

Procedure

  1. Extract the contents of the SAP Cryptographic Library installation package.

  2. Copy the library file and the configuration tool sapgenpse.exe to the SAP Web Dispatcher's library path. For this documentation, we use the directory C:\Program Files\SAP\SAPWebDisp.

    Recommendation Recommendation

    Check the environment variable LD_LIBRARY_PATH. If it is set, copy the library file to this directory.

    End of the recommendation.
  3. Check the file permissions for the SAP Cryptographic Library. If, for example, you copied the library to its location using ftp on UNIX, then the file permissions may not be set correctly. Make sure that the user that runs the SAP Web Dispatcher is able to execute the library's functions.

  4. Create a subdirectory called sec and copy the ticket file to this directory. This is also the directory where the SAP Web Dispatcher's PSEs and credentials are to be located.

    Location of the SAP Cryptographic Library

    C:\Program Files\SAP\SAPWebDisp\sapcrypto.dll

    Location of the License Ticket

    C:\Program Files\SAP\SAPWebDisp\sec\ticket

    End of the example.
  5. Set the environment variable SECUDIR to the directory where the library is located.

  6. If it is not already set, set the environment variable LD_LIBRARY_PATH to the directory where the library is located.

Result

The SAP Cryptographic Library is installed on the SAP Web Dispatcher.
