lsb

Hide string data in the least-significant bits of an array. It's an easy way of, say, storing information in images invisibly. Note that if you're trying to hide something important you should probably use something else :)

Installation

$ npm install lsb

Usage

require('lsb').encode(channel, stegotext, [iterator])

Where channel is the array to hide the stegotext string in. iterator is an optional callback for determining the index of each hidden byte, if you want to get tricky.

require('lsb').decode(channel, [iterator])

Once encodeded, use this on the same channel array to return the hidden string. If you used an iterator callback before, you'll need to use it again here or you'll get garbage text.
