File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum. This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files. A more popular approach is to generate a hash of the copied file and comparing that to the hash of the original file. WebFeb 22, 2024 · Hashing is carried out in three steps: Hash functions: A hash function is a cryptographic algorithm which cuts up data of different lengths completely, separates it and converts it to character strings of the same length. These hash values are much shorter and more compact than the original values.
