Strogonoff is a Go package to hide text on JPEG images.
It is called Strogonoff because the technique of sending information by concealing the message is called Steganography and this package was implemented with Go language. Besides that, I love strogonoff, a typical Brazilian meal.
99% of the code is from go lang "image/jpeg" package. I modified it to encode information on the LSB bits of the frequency components of the luminance channel for each 8x8 block, since the human eye is not well suited to perceive brightness differences on small regions.
TODO. See the tests
