[popcakjm] Fun with SHA-512

Some strings with interesting SHA-512 checksums.

Decreasing checksums

Numbers: 0 5 61 317 347 1533 12372 168105 215638 288946 396799 828099 1225126 1563153 1839773 2028205 2564482 6899310 20137006 58927867 164967769 186467368 317388584 2280957771 3949194172

Globally the largest: SKQCJEQ = ffffffff d53a1074 6cd0d470 77db3a46 9e7c893f d2f48a5e a243c043 4dad6a6c 4e8b9b94 118c25b4 1fd13d17 c086712a f04dcd97 31bf1c6a 6f883bb7 3cfdd3ee

Globally the smallest 3949194172 = 00000000 01b99889 c891f246 8c618149 cb6865b9 33cca31e ddb353de 09746b54 0616ba69 c5f5ff99 2c6d6177 427daf1c b46a4c5c 08625263 a615fbf3 eeaae178

All words up to 7 letters, and numbers up to 10 digits were searched ordered by Perl's magic ++ operator. The 11-digit record 11256569232 was a bonus for letting the program run slightly too long.
