tell-it-cypher

Instructions

FINALLY, you got the names. But you could forget it... loose it... How could you write it without puting the surprise in danger?!

Create a tell-it-cypher.mjs script that:

  • Takes a file as first argument
  • Takes one of these keywords as second argument:
    • encode: convert your file to base64, then save the result in a cypher.txt file.
    • decode: convert your file from base64, then save the result in a clear.txt file.
  • Could take a string as third argument and use it as the new file name. Extension must be precised.
