steganography

golang Implementation LSB steganography any data

inspired by stegify

Why duplicate implementations, Because I want to hide any data in the image, not just the image.

This is just the beginning, I hope to get your advice

Install

go get -v -u github.com/zhcppy/steganography/cmd/stego

or

git clone https://github.com/zhcppy/steganography

make install

Use

stego -h

Extension

Implementing interface about Steganography

type Steganography interface {
	GetCarrierFileName() string // get image carrier
	InputData() ([]byte, error)
	OutputData(data []byte) error
}
