You can just hide your encrypted files such as .jpg, .gif, .doc, .pdf etc inside a .WAV file (the data becomes just part of the audio noise floor) then convert into a AAC lossless audio file using iTunes (which hides the Steganos header) using Steganos Security Suite, even the NSA (Oops now they know about it) would be pretty much clueless. You can then store the AAC files just about anywhere such as on an email mailbox, hosted ftp domain, mp3 player, Archos Media player, iPhone etc.

To get your data back, just convert the AAC audio file back to a .WAV then drop the .WAV file into Steganos Security Suite (which will ask for the encryption password). Steganos will then plop out the unencrypted file.

Here is a screenshot. The 'Welcome to the National Security Agency - NSA_CSS.mht' file is hidden in the '01 Golf Girl.m4a' file.

The long password (>700 bits) would be pretty tricky to unencrypt even if anyone knew that the file '01 Golf Girl.m4a' file was even hiding an encrypted file in the audio file noise floor anyway.
