Kata

In this kata, you need to code a simple polyalphabetic encryption tool. Given is the method Encrypt, which has two parameters. At first, there is the string text, which includes the text we want to encrypt and the string key which we need to encrypt/decrypt our text.

If the key is smaller than the text, repeat the key.

[Attention] This is only a beta, so it could be possible that there are some bugs.

Here is a description: https://en.wikipedia.org/wiki/Polyalphabetic_cipher

You start with the following method:

public static string Encrypt(string text, string key)
{

}
