Problems with CRC32

[royce]

hashcat's crc32 implementation expects a second field. 

From the example hashes:

5. You can consider the second part as a “salt”. If it is equal to 00000000, the CRC32 code will be considered as “not salted”

Code:

$ echo -n 'hashcat' | tools/test.pl passthrough 11500
c762de4a:00000000

So if you append ':00000000' to your CRC32s, you should be good to go.
