About MurmurHash2
MurmurHash2 is a non-cryptographic hash function created by Austin Appleby in 2008. Its name comes from the core operations it uses: multiply (MU) and rotate (R). This tool produces 32-bit output.
How it works: MurmurHash2 processes data in 4-byte blocks with multiply and bit-shift operations, producing good distribution quickly. It is designed for performance, not cryptographic strength.
MurmurHash2 is popular in hash tables, caching systems, and databases because it is fast and spreads well. The newer MurmurHash3 is generally recommended for new projects due to better distribution and robustness.
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 MurmurHash2 hash?
A MurmurHash2 hash is 32-bit long (8 karakter heksadesimal / 8 hexadecimal characters).
Is my data sent to a server?
No. The MurmurHash2 hash is computed entirely in your browser. The text you enter never leaves your device.
