BLAKE2 – simpler, smaller, fast as MD5

The cryptographic hash function BLAKE2 is an improved version of the SHA-3 finalist BLAKE. Like BLAKE or SHA-3, BLAKE2 offers the highest security, yet is fast as MD5 on 64-bit platforms and requires at least 33% less RAM than SHA-2 or SHA-3 on low-end systems.

BLAKE2 comes in two flavors:

  • BLAKE2b (or just BLAKE2) is optimized for 64-bit platforms—including NEON-enabled ARMs—and produces digests of any size between 1 and 64 bytes
  • BLAKE2s is optimized for 8- to 32-bit platforms and produces digests of any size between 1 and 32 bytes

via BLAKE2.

    Oh now you have laid out a challenge to the internet. By tomorrow it will be listed as Blake2 Fastest Crypt and short cutted as bf2crypt which people will use to replace bfcrypt (because 2 is better right?)

    Have a good week
