Encryption

You can now encrypt PDF documents to the 256-bit level in Acrobat 9, either by creating encryption via security certificate (using an preexisting Digital ID or one-create on the spot with Acrobat), or using the encryption via password feature (picture below). On this page, you can choose what level you what like the document encrypted. There is a drop down with compatibility options with the previous Acrobat versions, ie. Acrobat 7 & 8 can handle 128-bit AES, Acrobat 6 can handle 128-bit RC4, etc. as well as options to set passwords for opening the document, etc. The security features are fairly significant, and Adobe provides easy access to show all the document's security settings, policies and more.
