[jira] Created: (PDFBOX-526) Add ability to read encrypted file &
write unencrypted flie
Add ability to read encrypted file & write unencrypted flie
-----------------------------------------------------------
Key: PDFBOX-526
URL: https://issues.apache.org/jira/browse/PDFBOX-526
Project: PDFBox
Issue Type: New Feature
Components: PDModel, Writing
Affects Versions: 0.8.0-incubator
Reporter: Adam Nichols
Currently, the COSWriter determines whether or not to use encryption, which makes sense, however there's no way to tell it you don't want to use encryption. So if you open an encrypted document, there's no way to write out an unencrypted document (you can write out a document without a password, but it'll still be encrypted). This means that encrypted documents can't be merged even if the password is known.
I have a patch which will allow writing out unencrypted documents. By default it'll work as it did before, but there's a new function which can be called to mark the document to be written out with no protection. I'll upload the patch soon.
