This C language functions support some statistical calculations
to determine the randomness of data:

    bit_entropy(bytea):     return Shannon bit entropy (value in [0.0-1.0]) of bytea
    byte_entropy(bytea):    return Shannon byte entropy (value in [0.0-8.0]) of bytea
    bit_entropy(bytea):     return Pearson chi-square stats of bytea

Feel free to use and modify this source as you want.
Use at your own risk.
