Steganography Online Codec SDK for Ruby

Steganography Online Codec allows you to hide a password encrypted message within the images & photos using AES encryption algorithm with a 256-bit PBKDF2 derived key.

You can use it for free at:

https://www.pelock.com/products/steganography-online-codec

This SDK provides programming access to the codec and its encoding and decoding functions through a WebAPI interface.

Steganography is a term describing the art and science of hiding information by embedding messages within other, seemingly harmless image files.

In this case, the individual bits of the encrypted hidden message are saved as the least significant (LSB) bits in the RGB color components in the pixels of the selected image.

With our steganographic encoder you will be able to conceal any text message in the image in a secure way and send it without raising any suspicion. It will only be possible to read the message after providing valid, decryption password.

The preferred way to install the Web API SDK is via RubyGems.

gem install steganography-online-codec

require "steganography-online-codec"

The gem is published at https://rubygems.org/gems/steganography-online-codec
