            Description

            A community member has reported an encryption issue related to PDF-868. The posted file is another example of hex strings that start off with FEFF which would normally be a flag indicating a 4 byte encoding. I should have given the hole class an audit for PDF-868 but unfortunately didn't.

            Once the class is updated to use the raw value of the hex string the document decrypts correctly.
