File xxHash

Hash uploaded files with XXH32, XXH64, or the ultrafast XXH3 family (64-bit & 128-bit). Configure seeds and output formats to produce deterministic checksums for rapid integrity verification.

xxHash digest

Select a file to compute its digest.

Hash validation

Matching happens against the current output format (hex).

Select a file, choose an output format, and provide an expected hash to compare.

Seed

Provide a 32-bit seed (decimal or hexadecimal). Leave blank to use zero.

xxHash overview

xxHash is engineered for blazing-fast checksums on large data streams. XXH32 covers legacy pipelines, XXH64 improves collision resistance, and XXH3 (64-bit/128-bit) delivers the best modern throughput.

Seeds make it easy to partition hash spaces across workloads. Supply decimal seeds or prefix hexadecimal values with 0x. XXH64 and XXH3 accept two 32-bit halves that form the 64-bit seed—reuse the same pair for both text and file hashing to stay consistent.

All hashing takes place on this device—no uploads or storage. For cryptographic guarantees use algorithms such as SHA-2, SHA-3, or BLAKE2 instead.
