Message Encoder

How It Works

The Message Encoder will encode and decode messages for you based on a simple encoding scheme.

The scheme works as follows:

• First you need to pick a key. The key can be any length but cannot have any repeating characters.
• The characters of the key, followed by the rest of the alphabet backwards, is then mapped to the alphabet normally. So for example, if the key was plumb then it would look like this:

a b c d e f g h i ...

p l u m b z y x w ...

• Now every character is replaced with it's corresponding character and you have you encoded message. To decode it, simply do the reverse.

This is only a simple encoding scheme. It is easily cracked. For that reason it is great for a variety of activities you may want to put together for a class or team challenge etc.
