picsg

A tool for steganographing information in a picture encoded using the Vernam cipher.

Synopsis

picsg [subcommand]

where subcommand is one of the following:

  • encode <text> <output-path> [--img <image-path>]
  • encode file <file-path> <output-path> [--img <image-path>]
  • decode [--img] <encoded-path> <key-path> <output-path>

Examples

  • Encode text using the Vernam cipher to the file hello.enc and create a file hello.enc.key with a key to decode the hello.enc file.

    picsg encode "ABC" hello.enc

  • Decode the hello.enc file using key and print to the standard output

    picsg decode hello.enc hello.enc.key -
