Have Fun with Encryption

(To the tune of "Walk Like an Egyptian" by The Bangles)

All these messages come and go
From Alice and Bob, to and fro.
If they don't encrypt (oh whey oh)
The warden their secret plan will know.

Clear-text messages they can't send.
They've got a good cure for this threat:
A private key (oh whey oh)
The problem is if they've never met

How to secretly send a key? Well..
Ay oh whey oh, ay oh whey oh
Have fun with encryption

You use RSA, take your text
Encrypt it using the public key
And to decrypt (oh whey oh)
The private key's what you're gonna need

If the warden sees cryptic code
He'll figure out something's being planned
Steganography (oh whey oh)
From plain sight the message is hidden

Hide your text in a bitmap file and
Ay oh whey oh, ay oh whey oh
Have fun with encryption

Change your text into hex, split and pack
Shift some bits, then you change it back
Make it hard, you know, (oh whey oh)
For hackers to figure out and crack

Algorithms are all around
There's Caesar and Triple DES
And RSA (oh whey oh)
And Blowfish and more, but I digress

There's the Japanese with their FEAL
The GOST boys are at the Kremlin
And the Chinese know (oh whey oh)
Decipher with Chinese Lottery

Spread your code all around the globe and
Ay oh whey oh, ay oh whey oh
Have fun with encryption
Have fun with encryption
