WebFeb 11, 2024 · A checksum is the outcome of running an algorithm, called a cryptographic hash function, on a piece of data, usually a single file. Comparing the checksum that you generate from your version of the file, with the one provided by the source of the file, helps ensure that your copy of the file is genuine and error free. 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. inc eyewear
