Text BLAKE2 Hash

Compute BLAKE2b or BLAKE2s digests with optional keyed hashing. Configure digest length to match your target system without leaving the browser.

Variant

Digest length (bytes)

1–64 bytes (128 hex chars max).

Key (optional)

Keys longer than 64 bytes are rejected. Leave blank for standard hashing.

Input text

Text BLAKE2 hash

Enter text above to generate a BLAKE2 digest.

Hash validation

Enter a target hash to validate.

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.
