Copialer

Tool to encode and decode text using copiale cipher. Inspired by this video on the this cipher.

Main Functions

• Generate cypher key file
• Encode text using key
  • Read from txt file
  • Output to txt file
  • Read from STDIN
  • Output to STDOUT
• Decode text using key
  • Read from txt file
  • Output to txt file
  • Read from STDIN
  • Output to STDOUT

TODO:

• Input argument flags for settings
• STDOUT interface & prompt
• Cipher Logic
• Get base charset
• Create first keyfile

Notes:

• Need better charset files, using the full set returns too many <?>. Using the chinese set is cool but limited.
• Need to find a way to replace the letter with one of the replacements for each instance not the same replacement across the whole document.
• Ideas for cli options
  • Flag for interactive mode
  • Flag to encode or decode
    • Require keyfile for decode (Not a cracking tool lol)
  • Flag to only generate keys
  • Flag for charset (used to create keyfile)
  • Flag for keyfile
    • If no keyfile, generate one on encode
  • Flag for input-file
    • Default to STDIN
  • Flag for output-file
    • Default to STDOUT
• Update naming, right now its very confusing. Start on paper, draw it out lol
• Refactor code. Does it even need to have async calls?? I dont think so.
