2] Using NLstego to embed text in another (generated according to the -m= model text) text (to encode and to decode):
Example encode: cat svn_test/trunk/ludics_secret | java -Xmx400M -jar nlstego-0.9-dev.jar -m=experiment/crying/crying e > steg_test Example decode: cat steg_test | java -Xmx400M -jar nlstego-0.9-dev.jar -m=experiment/crying/crying d3] Using steghide to embed text in a bmp image:
steghide embed -cf conspire81bw.bmp -ef conspire.txt and to decode: steghide extract -sf conspire81bw.bmp
