Powertoys: Generate checksums from file

Created on 9 May 2019  路  9Comments  路  Source: microsoft/PowerToys

Without a additional tool you can麓t fastly verfiy files with a checksum. You can only use the cmd:

eg. CMD:
certutil -hashfile SHA256

Possible algorithm:
MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512

It would be great to have these settings in a new tab "Checksum" by right clicking on a file, where all checksums listed (which can be calculated by certutil) .

There should be a field where you can copy in an existing checksum and compare it with the calculated ones. If it matches, the matching hash could be marked.

Wasn't this one of the options in Send to X? If not, that seems like a very good place for it to live.

Powershell has this, I want this as well. awesome idea!

@belg4mit good idea!

Feels like a good addition for #641 as a larger enhancement ... powermenu

it would be great to add this to the file property tab too.

An interesting option, which I currently use, is Hashcheck. It adds an item in the context menu and a tab on the Property window. It is also capable of calculating hashes for folders, recursively. Supports all the suggested algorithms and is BSD 3-Clause licensed.

I was about to open this issue, but want to point out that it will duplicate this functionality for anyone with 7-zip installed so it'd be nice to disable the feature or have PT replace basic 7-zip functionality.

example of shell extension for hashing
7-zip shell extension for folder context menus in File Explorer includes the hashing suite
