If anybody ever chooses to play around with my HMAC cipher, be sure to 
remove the call to the PRNG that is used to create the random numbers in 
the plaintext. Remove the call and replace it with a TRNG. It is meant 
to use a TRNG, but my experimental implementation uses Java's prng. My 
cipher is not even meant to be used with a CSPRNG! It needs a TRNG, damn 
it! I think it should be hard to find a period in a TRNG. For instance, 
is this a number? Think of a base 10 number where each digit uses a TRNG 
for its value, 0 through 9.

A decimal expansion with regard to digits, for instance:

TRNG().[TRNG(), TRNG(), TRNG(), ...]

Is this a number, or not a number.

A 10-ary die should be able to do this, right?

Here is an example of my HMAC Cipher example. You should all be able to 
examine the plaintext because it was encrypted using the default key. 
Now, keep in mind, that if I encrypted this again, it would have a 
different ciphertext. This is where I _really_ need to use a TRNG in a 
real impl, so to speak...
