Ted, I think you are confusing matters.

md5 is a cryptographic hash, it surely transforms text into bit soup,
but that is not not the same a an encryption function. For an
encryption function, you want to have a corresponding computationally
feasable decryption function. For hashes you're better off if no such
function exists. Also, many texts have the same md5 output. For an
encryption function that would be a major problem.
