A checksum file is a small file that contains the checksums of other files. There are a few well-known checksum file formats. Several utilities, such as md5deep, can use such checksum files to automatically verify an entire directory of files in one operation. The particular hash algorithm used is often indicated by the file extension of the checksum file. WebFileHash[file] gives an integer hash code for the contents of the specified file.

"WebAug 30, 2024 · 12. A hash is a one-way digest function. It takes a number of input bytes and computes a fixed-length value from it. If you compute the same hash again, you get the same result. Generally the numeric value of the length of the input is not considered, as the data is inherently changed if you change the length. Hashes cannot be decrypted. " - File hash algorithm
