This will succeed instantly and be 100% accurate because the input space (10,000) is smaller than the CRC32 space.
If CRC32 can be reversed mathematically using custom scripts, why use Hashcat? hashcat crc32
hashcat -m 11500 -a 6 -O hash.txt rockyou.txt ?d?d This will succeed instantly and be 100% accurate
If CRC32 can be solved mathematically, why use a brute-force tool like Hashcat? hashcat crc32
