BLAKE2 and BLAKE3 generator: what it is for
Calculate BLAKE2b (512 and 256 bits), BLAKE2s-256 and BLAKE3 hashes of a text or file. They are modern hash functions, faster than MD5 and as secure as SHA-3, used in backups, file systems, cryptocurrencies and download checks.
Everything is calculated in your browser: the text and files never leave your computer.
How to use
- Type the text or choose a file.
- See the BLAKE2 and BLAKE3 hashes.
- Copy the result.
When to use it
- Verify files with fast hashes.
- Test cryptography libraries.
- Generate content identifiers.
Frequently asked questions
What is BLAKE2?
It is a cryptographic hash function faster than MD5 and as secure as SHA-3. BLAKE2b is optimized for 64-bit processors and BLAKE2s for 32-bit processors and small devices.
And BLAKE3?
It is the newest version, even faster and parallelizable. It produces 256 bits by default and is used in file systems, backups and download verification.
Does the text leave my device?
No. The hash is calculated in your browser; nothing is sent to a server.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 are free.
