This will succeed instantly and be 100% accurate because the input space (10,000) is smaller than the CRC32 space.
: The second field after the colon is treated as a salt. If this value is , the checksum is processed as unsalted. hashcat crc32
On a single RTX 4090, Hashcat can test over . Yes, billion with a 'b'. That means an 8-character brute force finishes in under 10 seconds. This will succeed instantly and be 100% accurate
Plaintext: "hello" CRC32 (IEEE 802.3): 0x3610a686 Hashcat input: 3610a686 Hashcat can test over . Yes
Hybrid (wordlist + mask) hashcat -m 1400 -a 6 crc32.txt wordlist.txt ?d?d
In most CRC32 scenarios (e.g., bypassing a file integrity check), the goal is to find any input that matches the checksum, not necessarily the original input.
