TASK

Compare throughput of different hash algorithms

Measure how fast SHA-256, SHA-3, BLAKE2/3, and RIPEMD-160 hash a given input to choose the right algorithm for your throughput budget.

1

Hash algorithms trade off speed against security properties. BLAKE2/3 are faster than SHA-256 in software; SHA-3 is slower but hardware-resistant; RIPEMD-160 is legacy. Measuring actual throughput on your data size informs the choice.

Hash Crack Speed Reference →
Enter a sample input or specify a byte count. The tool benchmarks each algorithm and reports MB/s and hashes/sec, so you can compare on the same hardware.
3

Hash Calculator →
Compute the actual hash of your input with your chosen algorithm to confirm it works correctly on real data, not just benchmarks.
4

BLAKE2 / BLAKE3 Hash →
For maximum software throughput, use BLAKE2b (64-bit) or BLAKE3 (parallel). These often exceed 1 GB/s on modern CPUs.

Frequently asked questions

Why is SHA-3 slower than SHA-256?: SHA-3 uses the Keccak sponge construction which is inherently slower in software than SHA-256's ARX design. SHA-3's advantage is resistance to length-extension attacks and different cryptanalytic assumptions, not speed.
Should I always pick the fastest hash?: No. Speed matters for bulk data integrity and content-addressable storage. For password hashing or HMAC, you want a hash that is not too fast (to slow down attackers). For digital signatures, use the hash matched to your signature scheme (SHA-256 for ECDSA/Ed25519).
