You probably encrypted the file with a user password, but left the owner password as NULL. You should set the owner password to be the same as the user password when only one password is needed.
PDF Viewers other than Adobe's will open a file with a NULL password in either location. From: Khaled Hassen [mailto:khaled.has...@in-rgy.com] Sent: Friday, July 22, 2016 12:22 PM To: users@pdfbox.apache.org Subject: Encrypt pd file Hello, I have a request from my client to generate employee payslip on pdf file from SAP, encrypt it and send it by mail to the employee. For the encryption part I used the JAR file (PDFBox 1.8.12) that I downloaded from your website. I created SAP ABAP programme to call the JAR file. The testing were fine, the files were encrypted successfully and we were able to enter PWD when opening the files. We have a problem with the EE using iPhone and iPad, when they tried to open the file they were not asked to enter a password, the file was opened automatically. Please do you have an idea how to fix this issue. Thanks a lot.
