Hi,
I have PDFs which are password secured. Whenever I am removing the
security from "Password Security" to "No Security", it is asking password.
But there are few PDFs for which password is not asking and I am able to
remove the security. I am doing it using Adobe Acrobat professional.
The same, I want to use with Java iText api. I am able to find such PDFs
for which I am able to remove the security without giving password using the
method:
PdfReader.computeUserPassword.
For these PDFs, it is returning values in Byte but for other secured PDF,
it is returning NULL value.
Can any one please let me know how to reset the security for these PDFs
from "Password Security" to "No Security"?
Thanks in advance.
Regards,
Ashok
