• Decrypt Password Online

Want to improve this question? So it's for Stack Overflow.Closed 5 years ago.I need to be able to remove the security/encryption from some PDF documents, preferably with the itextsharp library. This used to be possible , but a more recent to the library means that solution no longer works.I know this can be done with the Aspose PDF library , but that appears to be an expensive option.EditSo all this time I thought I was in possession of the owner password for the document I was using to test this.

But in fact the password I had was the user password. The reason I thought it was the owner password was because it worked as the owner password and other values did not work. I believe the reason the user password worked in place of the user password was the fact that the PdfReader.unethicalreading field was set to true (it's a global flag that happened to be set elsewhere in code).

I am more or less the 'Dr. House' at iText Software in the sense that the support team only passes me customer questions that nobody else can solve. I don't know if you posted the question to the issue tracker, but if you post the question publicly, you address the 'Dr. House' inside me directly, which means you get an answer plus the attitude;-) I now realize that my answer nor Kurt's answer match the actual problem.

I appreciate the edit you've made. Prank programs blogspot comics. I've never tried opening a PDF with iText with the user password. It's very interesting to know that this used to work (it isn't supposed to).–Jan 11 '15 at 6:47.
