Thanks for the solution, its working.

Result of encryption is created a output pdf with password secured rite

Note: "owner_pw" contains the permission password and "user_pw" contain open document password.

And Decryption function it just remove the security password by removing owner_pw, but not user_pw

Please let me know , whether my understanding is correct.
