Cryptographic hash code

WebA cryptographic hash function essentially takes input data which can be of practically any size, and transforms it, in an effectively-impossible to reverse or to predict way, into a relatively compact string (in the case of SHA-256 the hash is 32 bytes). 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.
