Abstract
Encrypted content may be stored in a file wrapper with unencrypted content that provides information regarding the encrypted content. The file wrapper may be stored around the encrypted content or may be stored in front or behind the encrypted content. The unencrypted content may indicate, for example, that additional content in the file is encrypted. A TIFF-formatted file may be used to store the two portions of content. A TIFF file structure may have content stored in a plurality of images. The unencrypted content may be stored in a first image of a TIFF file. The encrypted content may be stored in a second image, third image, and/or additional images of the TIFF file.
