About FNV-1
FNV-1 (Fowler–Noll–Vo) is a family of non-cryptographic hash functions known for their simplicity and speed. Created by Glenn Fowler, Landon Curt Noll, and Phong Vo. This tool produces 32-bit output.
How it works: FNV-1 starts from an "offset basis", then for each byte multiplies the running value by an "FNV prime" and XORs it with that byte. The operations are very lightweight, making it very fast.
FNV is widely used in hash tables, indexes, and simple checksums because it is easy to implement and fast. For slightly better distribution, FNV-1a is usually recommended.
FAQ
What is the difference between FNV-1 and FNV-1a?
They are nearly identical; the order of the per-byte XOR and multiply is swapped. FNV-1a (XOR first, then multiply) generally gives slightly better distribution and is preferred.
Is FNV for security?
No. FNV is a simple non-cryptographic hash for hash tables and quick checksums, not for security. Use SHA-256/BLAKE3 for security.
How long is a FNV-1 hash?
A FNV-1 hash is 32-bit long (8 karakter heksadesimal / 8 hexadecimal characters).
Is my data sent to a server?
No. The FNV-1 hash is computed entirely in your browser. The text you enter never leaves your device.
