Description Author

This class can encrypt and decrypt text by mapping characters.

It can take a text string and encrypt it using two text strings that define which characters should be mapped to what other characters depending on the position of the character in the string.

The class can also do the opposite, i.e. take a previously encrypted string and invert the process to recover the original string.

The key strings with the characters to be mapped are configurable.

Description:

This class will encrypt and decrypt text using a cipher that determines the replacement character by a mapped character and position in the message.

Since the position is also considered, common words like 'the' will always be different in encrypted message.
