If installed with PIP:

steganopy [-h] [-v VALUES] [-t TEXT] [-f FILE] [-o OUTPUT] [-k KEY] source action

Utilize -h or --help parameter for additional help.

positional arguments:
  source                Picture source location.
  action                Specifies whether to be encrypting or decrypting.

  -v VALUES, --values VALUES
                        Values used for encryption. (default: rgb)
  -t TEXT, --text TEXT  Text to be added when encrypting is selected for "action" argument. (default: None)
  -f FILE, --file FILE  File location of text to be added when encrypting is selected for "action" argument. (default:
                        None)
  -o OUTPUT, --output OUTPUT
                        Specifies output file name. (default: None)
  -e ENCODING, --encoding ENCODING
                        Specifies the base the information is to be or is encoded in. (default: binary)
  -k KEY, --key KEY     Specifies key to use for xor operation. (default: None)

Additional Notes:

• The -t or -f option is necessary if the action argument is set to e or encrypt
• The following are accepted file extensions: png, jpg, webp, jpeg
• The following are accepted encoding bases: binary, trinary, quaternary, quinary, senary, septenary, octal, nonal

Examples

steganopy exampleimage.png e -t "test text" -v r

- Will only utilize the red values in the image to put the information in.

steganopy exampleimage.png e -t "test text" -o "newname"

- Will output the file with the name "newname" instead of the default name of the original filename with -steganopy appended to it.

steganopy exampleimage.png e -f exampletext.txt

- Will get text from the exampletext.txt file to use.

steganopy exampleimage.png e -e trinary

- Will encode the information in base 3 (trinary) instead of the default of binary.

steganopy exampleimage-steganopy.png d -v r

- When decrypting, the values used in encryption must be the same, otherwise errors may be thrown.

steganopy exampleimage-steganopy.png d -v r -o test

- When decrypting, you can also use the -o --output argument to have the information be outputed into the a text document with the specified name.
