 		This is probably a stupid question but what is the technique called for encrypting a word into a different word that is a different length?
Might be a Cipher but what kind?

 		I'm not sure what you mean DNA.

Steganography is used for embedding secret information within another document. This data could be encrypted.

Public-key cryptography can encrypt a word in to another string (the public key). It's only possible to decrypt this with the private key. *

Strong encryption is AES. At 192-bits and 256-bits, this provides great protection from being decrypted by brute force.

* Public-key cryptography is quickly becoming extinct (thanks to increased computing power). Elliptic curve cryptography is a great alternative, but it's patented and hard to find libraries for.

 		I looked up a few things since my post and found the one time pad to be strong but meaningless to the reader.

What I mean Stealth is this, using the word:

MIRCO

and encrypt it into another word that means something or nearly something and so:

MICRO
becomes
BRITTANY

I also found the Caesar cipher to be something similar to what I mean but it is weak compared to the One Time Pad
