WebBLAKE2 is a cryptographic hash function defined in RFC 7693 that comes in two flavors: BLAKE2b, optimized for 64-bit platforms and produces digests of any size between 1 and 64 bytes, BLAKE2s, optimized for 8- to 32-bit platforms and produces digests of any size between 1 and 32 bytes. WebHashing is the transformation of a string of character s into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption ...
