md5deep is a set of programs to compute MD5, SHA-1, SHA-256, Tiger, or Whirlpool message digests on an arbitrary number of files. md5deep is similar to the md5sum program found in the GNU Coreutils package, but has [...] additional features...
md5deep is FLOSS (source is on Github) with a somewhat peculiar license blurb:
At the time md5deep was originally written, Mr. Kornblum was a Special Agent with the United States Air Force Office of Special Investigations (AFOSI). As such, the program is considered to be a work of the United States Government. Under 17 USC 105, works of the United States Government are not eligible for copyright protection.
md5deep is composed of a set of 12 different command line executables, each one geared towards a different hashing method and OS bitness. Documentation is rather extensive.

As a contribution for the problem I brought to a recent discussion, here's a quick'n'dirty™ script to use md5deep to hash and sidecar any file dropped on it:
Code: Select all
@ECHO OFF :: Conditional clause below is a crude detector of OS bitness :: Allowing for running the corresponding executable :: Made by Midas, 2018-06-24 IF EXIST "%PROGRAMFILES(x86)%" (SET BOS=64 ) ELSE (SET BOS="" ) MD5Deep%BOS% -bk "%1" > "%~n1.md5"
