How secure is Safeguard PDF Security?
Safeguard PDF Security uses US Government strength encryption – the AES algorithm at it’s strongest strength, 256 bit. It would currently take todays fastest computer approximately 149 thousand-billion (149 trillion) years to crack a 128-bit AES key. Even with future advances in technology, AES has the potential to remain secure well beyond twenty years. For more information on AES see NIST’s AES fact sheet In addition, we don’t use third party plug-ins to control your secure document access. This ensures we are not open to weaknesses in the published APIs or security holes in the third party application. One of our competitors that uses this approach, has been compromised and found the only way to prevent hacking of their systems was via the legal system and a court writ! PDF documents are only decrypted for viewing in a secure, controlled environment, and are never made accessible unprotected. If a user does not have a license they cannot view your protected PDF documents.
