Cloak
From Just Solve the File Format Problem
Cloak by Insight Concepts is a Win32 encryption and steganography program.
Encryption uses a 256-bit Arcfour (RC4) algorithm and optional compression to create .clk files.
Steganography hides data in BMP, PNG, GIF, and TGA images. It requires a password and encrypts with Arcfour in the demo version, plus Blowfish and Rijndael (AES) in the paid version
Cloak Mail encrypts a message and inserts it into a message body that looks completely blank. Requires Outlook.
Cloak Viewer decrypts files from Cloak, and upon successful extraction, gives the option to erase the data from the image.
Decrypt HD decrypts files from Cloak v7 and Data Stealth v1.0.
