Original GitHub issue: https://github.com/clechasseur/pathcopycopy/issues/39

https://github.com/okdshin/PicoSHA2 is an MIT-licensed C++ component, that may be useful to accomplish a SHA-256 file hash.
https://msdn.microsoft.com/en-us/library/system.security.cryptography(v=vs.110).aspx Microsoft has SHA-256 / 384 / 512 functions in its libraries.

This functionality is useful in projects such as maintaining content found on https://chocolatey.org/packages

I'll keep this as a possible enhancement, but this is a bit specific, I think. Still, interesting idea.

@clechasseur There's some other tool out there that I found, that has similar functionality; but I believe required a paid license. It has also been standard practice for years to "compare the file hash" of downloaded content, if you're paranoid about security; so there is definitely a use case here. I'm strung between some C# and JS projects, else I'd pitch in myself on this.

7zip installs a context menu entry that provides this if I'm not mistaken

@penCsharpener (checks) Yeah, there is a CRC-SHA menu context option on systems that have 7-zip correctly installed. The context menu seems to be really hit or miss on when I load it onto systems. :/

I use file menu in total commander software as it has a create file checksum feature. Given you can add custom commands to pathcopycopy you could use a general command line tool that takes checksum method (CRC32,MD5,SHA1/256/512) and file name as command line arguments. You might like to look at a script that uses: certutil.exe (I think it is only found on win 7 or higher); or powershell cmdlet . I have not found any tools that run on older windows.

http://implbits.com/products/hashtab/
is a snapin as a dll file directly on the explorer, right Mouse, Property's and one of the tab ;)
Pathcopy it's the wrong place for it ;)

I think there are other options out there… I myself use the 7-zip menu and it seems to work fine. I'll close this.
