There is a problem with regard to the cyphertext being virtually identical
when one changes a single character in the plaintext.

So, encrypting "Christopher" would give a cyphertext. Now changing the
plaintext to "christopher" would give the same cyphertext with only one
character changed! This is simply terrible.

I think there is a way around this such that changing a single character in
the plaintext would produce radical changes in the cyphertext.

Humm... Need to think.
