xxHash Text Generator
Produce xxHash32 or xxHash64 digests for any text input. Adjust seeds for deterministic sharding or compatibility. Need to hash files instead? Use thexxHash file tool →
Text xxHash
Compute xxHash digests across XXH32, XXH64, and the high-performance XXH3 family (64-bit or 128-bit). Every variant runs locally with optional seeds for deterministic fingerprints.
Current length: 0 characters
Enter input text and configure seeds to generate a digest.
Matching happens against the current output format (hex).
Enter a target hash to validate.
Provide a 32-bit seed in decimal or hexadecimal (prefix with 0x). Defaults to zero.
xxHash overview
xxHash is a lightning-fast, non-cryptographic hash designed for streaming. XXH32 maximizes compatibility, XXH64 ups collision resistance, and XXH3 pushes throughput further with both 64-bit and 128-bit flavors.
Seeds let you decorrelate hash results across contexts. Use decimal (e.g. 1234) or hexadecimal inputs (0x4d2). XXH64 and XXH3 expect low/high 32-bit words that together form the 64-bit seed.
All computation happens locally. Need to hash files with the same parameters? Switch to the xxHash file tool and reuse the exact seeds for consistent results.
