: CRC32 is extremely fast on modern GPUs, making it trivial to find multiple collisions for a single 32-bit value. Common Applications Data Integrity Verification
| Property | Details | |----------|---------| | Output size | 32 bits (4 bytes / 8 hex characters) | | Design purpose | Error checking (e.g., network packets, ZIP files, PNG chunks) | | Cryptographic security | None (broken for integrity/authentication) | | Speed | Extremely fast (hardware accelerated in CPUs) | | Collision resistance | Trivial to generate collisions |
While CRC32 is technically a checksum and not a cryptographic hash, Hashcat supports it for identifying collisions or recovering original data that matches a known 32-bit checksum value. Key Usage Details Format requirement
