    Length of O string of the encryption dictionary (AES256)

    fcreator Level 1

      The PDF reference states that O string of encryption dictionary is 48 bytes long, but when I open PDF file (Acrobat 9 or X or XI), in hex editor, the actual length of O string is 127 bytes.

      The same applies to U string. What is correct?

      Thanks.
