hypnosec (2231454) writes "BLAKE2 has been recently announced as a new alternative for the existing cryptographic hash algorithms — MD5 and SHA-2/3. With applicability in cloud storage, software distribution, host-based intrusion detection, digital forensics and revision control tools, BLAKE2 performs a lot faster than MD5 algorithm on Intel 32 and 64-bit systems. Developers of BLAKE2 insist that even though the algorithm is faster, there are no loose ends when it comes to security. BLAKE2 is an optimized version of the then SHA-3 finalist BLAKE."
