Hi Luan,
This question should have been created in a different forum as this has no relation to the database whatsoever, so you may want to move it to the correct forum or create a new thread and close this one. As you wish.
In any case, I would recommend you to follow the steps in SAP Note:
662340
662340 - SSF Encryption Using the SAPCryptolib
and
510007
510007 - Setting up SSL on Application Server ABAP
As this error usually comes up when there are missing profile parameters or perhaps a spelling mistake was made.
Hope this helps.
Best Regards,
Hugo
