Now that I've done the encryption, I'm trying to decrypt (imagine that).
My goal is to read in an encrypted File, and write out that same file
without the encryption. I've tried a few different things, and I seem to
be very close. The file I write out can be opened in Adobe Acrobat Reader
and it displays without entering a password, however if I read in the file
with PDFBox, doc.isEncrypted() will return true. I opened it in a hex
editor and it does look like it's encrypted, so I'm guessing what's
happening is that it's being encrypted with an empty password. I wanted
to just remove the encryption all together. Here's my code:
AccessPermission ap = new AccessPermission();
StandardProtectionPolicy spp = new
StandardProtectionPolicy(null, null, ap);
StandardDecryptionMaterial sdm = new
StandardDecryptionMaterial(password);
StandardSecurityHandler ssh = new
StandardSecurityHandler(spp);
ssh.decryptDocument(doc, sdm);
doc.protect(spp);
doc.save(fos);
I tried it without doc.protect(spp) but then the old policy still applied
so it was still encrypted and the password was still needed to open it.
Anyone know how to completely remove the encryption.
