About

This is a simple cli-application using crates

  • modernized_vigenere
  • clap

Please check https://en.wikipedia.org/wiki/Vigen%C3%A8re_cipher for a brief definition of the Vigenere cipher.
As you can see, this encryption/decryption is based on shifting the letters, based on a en/de-cryption phrase.
But time has changed since the 16th century:
The dominent way to pass information, is not via paper (using the alphabetic letters) any more.

Today, we use files ( and not only ASCII-files ).
So this modernized lib does not shift alphabetic letters but bytes !

Therefore this lib can be used to en/de-crypt not only ASCII-files, but any kind of files (yes, even binaries),
and is able to use not only Strings but also (binary) files as a phrase for en/de-cryption.
