About BLAKE2s
BLAKE2s is the sibling of BLAKE2b, designed for 8-bit to 32-bit platforms (microcontrollers, embedded systems, memory-constrained environments). Its default output is 256 bits (64 hexadecimal characters).
How it works: like BLAKE2b, BLAKE2s uses a ChaCha-based core but with 32-bit words, making it more efficient on smaller processors. Its security is strong and resistant to known collision attacks.
Use BLAKE2s when targeting 32-bit devices or when a 256-bit output is enough. For modern 64-bit servers and CPUs, BLAKE2b is usually faster. Both are much faster than SHA-2 with comparable security.
FAQ
How long is a BLAKE2s hash?
A BLAKE2s hash is 256-bit (default) long (64 karakter heksadesimal / 64 hexadecimal characters).
Is my data sent to a server?
No. The BLAKE2s hash is computed entirely in your browser. The text you enter never leaves your device.
