Blake Hash FAQ
What is Blake2/Blake3?
Blake2 and Blake3 are modern cryptographic hash functions designed as faster and more secure alternatives to MD5 and SHA-1.
Is Blake secure?
Yes. Both Blake2 and Blake3 are considered secure and are used in protocols, blockchains, and cryptographic libraries.
Where is Blake used?
Blake is used in file integrity checks, blockchain technologies, signatures, and general hashing tasks.
What is the difference between Blake2 and Blake3?
Blake3 is faster and more scalable, while Blake2 has longer adoption history and compatibility.
Can I use Blake for password hashing?
No. For passwords, use Argon2 or PBKDF2 instead, since they are memory-hard and designed for key derivation.
About Blake Hash Functions
BLAKE2 and BLAKE3 are modern cryptographic hash functions designed to replace older algorithms such as MD5 and SHA-1, which are now considered broken. They offer collision resistance, speed, and strong security guarantees.
Why New Hash Functions?
- MD5 and SHA-1 are insecure and vulnerable.
- SHA-2 (SHA-256, SHA-512) remains secure but can be slower in some contexts.
- BLAKE2 is a secure, faster drop-in replacement in many cases.
- BLAKE3 improves parallelism and scalability for modern hardware.
BLAKE2 Overview
Released in 2012, BLAKE2 builds on the SHA-3 competition finalist. It’s widely deployed because it’s faster than MD5 and SHA-2 while maintaining strong cryptographic guarantees. BLAKE2 supports 256-bit and 512-bit digests and is used in file integrity checks, MACs, signatures, and some blockchain frameworks.
BLAKE3: Next Generation
Published in 2020, BLAKE3 improves upon BLAKE2 with a Merkle-tree design, SIMD acceleration, and excellent scalability. Beyond standard hashing, BLAKE3 can serve as a key derivation function, a MAC, or even a random number generator. This versatility makes it one of the most practical primitives today.
Comparison
| Feature | BLAKE2 | BLAKE3 |
|---|---|---|
| Year Released | 2012 | 2020 |
| Performance | Faster than SHA-2 | Highly parallelized |
| Use Cases | Signatures, MACs, integrity | Hashing, RNG, KDFs |
Best Practices
- Use BLAKE2 for compatibility and proven deployments.
- Prefer BLAKE3 for new projects requiring speed and scalability.
- Avoid legacy algorithms such as MD5 and SHA-1 entirely.
- For password storage, use memory-hard functions like Argon2 or PBKDF2 instead of plain hashing.
This free tool demonstrates BLAKE2 and BLAKE3 in action. All operations run entirely client-side, meaning your data never leaves your device.
