Developer's Description

OTP-Steg is free software that allows you to embed a message into a PNG image file. OTP-Steg uses one-time pad (OTP) encryption in conjunction with least significant bit (LSB) image encoding.

There are three programs included:

1. Encrypt -- Allows you to encrypt/embed a Unicode message (any language alphabet or characters are acceptable).

2. Decrypt -- Decrypt the message using the selected image and key files.

3. Generate Keys -- Allows you to generate extremely secure (mathematically unbreakable) one-time pad image keys for use with encryption and decryption.

The "One-Time-Pad" encryption methodology is regarded historically and currently as the most secure of all forms of encryption. When used properly, it has never been broken.
