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 d

3] 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
