Standard usage is:
stego.py [-h] [-d] [-a] -i FILE [-o FILE] [-s STRING] [-f FILE]
Stego: DCT and LSB Image Steganography
Optional arguments:
-h, --help Show this help message and exit
-d Set method to decode, default is encode
-a Set encoding/decoding algorithm to LSB, default is DCT
-i FILE Specify input file name
-o FILE Specify output file name (optional)
-s STRING Specify message to encrypt
-f FILE Specify text file containing message
LSB encryption example:
stego.py -i inputFile.jpg -a -s 'message to encrypt'
DCT encryption example:
stego.py -i inputFile.jpg -s 'message to encrypt'
LSB decryption example:
stego.py -i inputFile.jpg -a -d
DCT decryption example:
stego.py -i inputFile.jpg -d
