Check using analyze.c on 10Mb file containing zeros

        File size: 10240000 bytes
Char distribution: 100.000000%
  Char redundancy: 0.000000%
     Char entropy: 7.999982 bits/char
 Compression rate: 0.000000% (10240000 => 10243131 bytes)

For comparision, AES result:

        File size: 10240032 bytes
Char distribution: 100.000000%
  Char redundancy: 0.000000%
     Char entropy: 7.999981 bits/char
 Compression rate: 0.000000% (10240032 => 10243163 bytes)

Check using 'ent'

(see http://www.fourmilab.ch/random/)

Entropy = 7.999982 bits per byte.

Optimum compression would reduce the size
of this 10240000 byte file by 0 percent.

Chi square distribution for 10240000 samples is 248.61, and randomly
would exceed this value 60.09 percent of the times.

Arithmetic mean value of data bytes is 127.5026 (127.5 = random).
Monte Carlo value for Pi is 3.142529353 (error 0.03 percent).
Serial correlation coefficient is 0.000282 (totally uncorrelated = 0.0).

For comparision, AES result:

Entropy = 7.999981 bits per byte.

Optimum compression would reduce the size
of this 10240032 byte file by 0 percent.

Chi square distribution for 10240032 samples is 274.74, and randomly
would exceed this value 18.90 percent of the times.

Arithmetic mean value of data bytes is 127.4883 (127.5 = random).
Monte Carlo value for Pi is 3.142633148 (error 0.03 percent).
Serial correlation coefficient is -0.000300 (totally uncorrelated = 0.0).

Check using dieharder

I ran the cipher against the dieharder test suite this way:

dd if=/dev/zero of=/dev/stdout | ./twenty4 00000000000000000001 1 | dieharder -g 200 -a

Output:
