If I do this:

Code:

$ ./swordfish
>>}###@>---- define X=(n{ABCDEF})
>>}###@>---- XXXXXX
0F5C7E
9833F3
9713BE
1EBE49
195969

>>}###@>----

I can generate random hexadecimal numbers. Password generators are very close to being random number generators. So it is fair to ask a password generator to pass tests intended for a random number generator. I did this:

Code:

$ ./swordfish "define X=(n{ABCDEF})" "format 1000000" "X<80>" > hex.txt
This command took 13711 seconds.
$

At that point I had one million lines of hexadecimal numbers, each 80 characters in length. This is exactly the input format needed by the asc2bin program of the diehard test suite. I ran diehard on the data file, selecting all 15 tests. The data passes all 15 tests. The results are attached.

diehard.txt (56.2 KB)
