About MurmurHash3
MurmurHash3 is a refinement of MurmurHash2, also by Austin Appleby. It improves distribution and removes some weaknesses of the earlier version. This tool produces 32-bit output (other variants support 128-bit).
How it works: MurmurHash3 uses better constants and a finalization mix to ensure each input bit affects the output evenly, so collisions are rarer in hash-table use.
MurmurHash3 is the go-to when you need a quality non-cryptographic hash: hash tables, bloom filters, sharding, and data distribution. Still not for security — use a cryptographic hash for that.
FAQ
Is MurmurHash for security?
No. MurmurHash is a non-cryptographic hash for hash tables and data distribution, not for security. For security use SHA-256 or BLAKE3.
What is the seed option for?
The seed changes the starting value so the same input yields a different hash. Useful for hash-table randomization. Default 0; set it in "More settings".
How long is a MurmurHash3 hash?
A MurmurHash3 hash is 32-bit long (8 karakter heksadesimal / 8 hexadecimal characters).
Is my data sent to a server?
No. The MurmurHash3 hash is computed entirely in your browser. The text you enter never leaves your device.
