PDFLiberator is just a simple utility for removing the owner password from a PDF document. There are a lot of cases where a public document has been inappropriately protected with an unknown owner password. An owner password prohibits modifications of such a document. PDFLiberator uses the iText (http://www.lowagie.com/iText/) library to remove the owner password. You will need a JVM and the iText runtime libraries. Because iText depends on the BouncyCastle library, you will also need to download it from http://www.bouncycastle.org/. An example invocation: java -classpath bin:iText-2.1.5.jar:bcprov-jdk15-142.jar com.stackframe.pdfliberator.PDFLiberator file.pdf When - is supplied as the only argument, the PDF file to process is read from standard input and the modified version is written to standard output. If no arguments are supplied, a GUI is presented for interactive selection of files to process. -- Gene McCulley mcculley@stackframe.com
