Description of Vernam Cipher

Using this app, you can create and share secret keys that you can then use to encrypt and decrypt messages using the Vernam Cipher. This implementation acts as a one time pad as it discards the part of the key used to encrypt/decrypt messages.

Source code is available at https://github.com/jeffisaak/vernam_cipher
