BLAKE2b
RecommendedBLAKE2b is a cryptographic hash function faster than MD5 and SHA-1 while being as secure as SHA-3. It was designed as a faster alternative to SHA-2 and is used in many modern applications including libsodium and WireGuard.
What is BLAKE2b?
BLAKE2b is a recommended cryptographic hash algorithm that produces a Configurable, up to 512 bits (typically 256 or 512 bits) output. BLAKE2b is a cryptographic hash function faster than MD5 and SHA-1 while being as secure as SHA-3. It was designed as a faster alternative to SHA-2 and is used in many modern applications including libsodium and WireGuard. It is classified as very fast in performance and commonly used for general-purpose secure hashing where speed matters and file integrity verification with strong security.
