Text BLAKE2 Hash
Compute BLAKE2b or BLAKE2s digests with optional keyed hashing. Configure digest length to match your target system without leaving the browser.
1–64 bytes (128 hex chars max).
Keys longer than 64 bytes are rejected. Leave blank for standard hashing.
Current length: 0 characters

Hash overview
BLAKE2 retains the speed of MD5 while offering SHA-3 grade security. Choose BLAKE2b for 64-byte digests or BLAKE2s when you need a smaller 32-byte output for embedded systems.
Every calculation runs locally. Refresh or close the page to drop all inputs and keys from memory.
