Fast secure hashing

The cryptographic hash function BLAKE2 is an improved version of the SHA-3 finalist BLAKE. Like 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. The core algorithm of BLAKE2 is derived from ChaCha, a stream cipher designed by Daniel J. Bernstein that has been proposed as a standard cipher for TLS.
