Hi,
We faced an issue where user is unable to open password protected PDF via Adobe Acrobat in Android device. Meanwhile we had tested opening the PDF via desktop & IOS Adobe Acrobat and able to open it as expected.
We had tested with various Android devices including vivo, Samsung, google pixel and etc.
The behavior is as below:
1. When user open the PDF via Adobe Acrobat Reader app
2. Adobe Acrobat will prompt the password input field
3. Entering correct password and proceed
4. App will return error msg - password is incorrect (using same password in desktop acrobat and able to open without any issue)
Below are the details/specs when we generating the encrypted PDF:
By default, encryption version 4 using AES with 128 bit key length is used for PDF 1.X, encryption version 5 is the most recent encryption method. It uses AES with a 256 bit key length and is only supported in PDF 2.0.
- We have tested and both PDF versions are unable to be opened in Android Acrobat PDF viewer.
- We have also tested and both PDF versions are able to be opened in Android Google Drive PDF, One Drive PDF, WPS office, Samsung default PDF viewer
I have attached the sample PDF document below for your reference. The password is S0440528E
May I ask what is the possible root cause here?
