opening encrypted pdf file using Appel application

Former Member — Tue, 12 Jul 2016 15:00:54 GMT

Hello All,

I have created ABAP program to generate payslip on pdf file, encrypt it and send it by mail to the employee. For the encryption I used JAR file and external command. It works fine. Under SOST the messages were created with the attached pdf files. And when you try to open the file it is asking for the pwd.

We have problem with the employee using Iphone and Ipad. When they open the pdf file it is not asking for the PWD the file opens automatically. It seems the issue occurs only with APPEL platform, we don’t have this issue with Androids.

Please do you have an idea how to fix this issue.

Thanks.

It's not Appel, it's Apple. (For a moment thought there was some novel application out there.)

Why is this an ABAP question? Is there something preventing you from typing "ios pdf password protection does not work" in Google?

Hi Jelena,

Thanks for your comments.

I put the question under ABAP section because the files are generated by ABAP program. I thought that I have missed some things that is causing the problem on APPEL platform.

For you information the employees using iPhone are receiving encrypted pdf files from others systems and they can't open the files with out the PWD. It is only with the pdf files received from SAP that they can open the files without PWD.

Thanks.

I'd propose this methodology to locate the issue (simplify the steps - ignore the email):

download the generated pdf file, before encryption. Do the password protection yourself, and make sure it works.
create another ABAP program which reads the PDF file and do the encryption. Make sure it works.
compare the PDF files at byte level (search for a utility, or write it yourself), with the one sent by email which has the issue.

Also you might want to clarify how exactly you do the password protection. Not sure how JAR format fits into the picture... It's essentially an archive format, so are you saying you are not actually sending a password-protected PDF but a password-protected JAR file? (And if so then why? There is a document on SCN on PDF, use Google.)

What is in the external command you are using?
