Jsteg (Luke Champine)
From Just Solve the File Format Problem
jsteg by Luke Champine is a Go-based steganography program to hide a file in a JPG or PNG.
It takes about 10-14 bytes of jpeg to store each byte of the hidden data.
Includes slink, a narrowly-focused command that embeds a public key in a jpeg, and makes it easy to sign data and verify signatures using keypairs derived from password strings
