Commonly-used file verification algorithms or checksums are:

  • MD5
  • SHA-256 and SHA-512: which are novel hash functions computed with eight 32-bit and 64-bit words, respectively.
  • …

macOS

Get an MD5 checksum:

  1. md5  [-pqrtx] [-s string] [file ...]

Get an SHA-256 checksum:

  1. shasum -a 256 [file]

Linux

Get an MD5 checksum:

  1. md5sum [file]

Windows

Install 7-Zip and then we can use the context menu to compute one file’s SHA-256 hash value etc.
