            Description

            ICEpdf is unable to open two Adobe 9 Pro encrypted files, one being password encrypted and the other certificate. Here are the results for the two sample files:

            - IP-article-beta-cert.pdf - Running this certificate encrypted file with 3.1.2 and 4.0-beta results in the following error dialog: "This may be the result of an invalid password or missing security provider" and the following exception:

                marking as resolved, as we support AES 128 encryption and can open most acrobat 9 files. However

                Work still needs to be done specifically in these two areas for full encryption support.
