Question

Is there a built-in method for computing an SHA-1 or MD5 hash in Windows 7?

Answer 1

There is no built-in utility, however Microsoft provides a command-line utility as a free download:

Availability and description of the File Checksum Integrity Verifier utility

Answer 2

It's not exactly built-in, but at least you don't have to download any new software to make it work. You can create a powershell script to compute the MD5sum of files. The actual script can be found here:

http://www.ahmadsoft.org/powershelljunkie/index.html

Copy that text into a file called something like, "ps-md5sum.ps1" and save it somewhere. When you need to compute the hash of a file, open up PowerShell in the directory of the file you need to check, and then run it:

[PS] C:\> ps-md5sum.ps1 file-of-choice.exe

And it should return the hash of that file.

Answer 3

There's nothing built-in. Might I suggest using HashTab?

Answer 4

Again, nothing built in, so I use HashCalc.

Answer 5

No built-in tools.

I use the HashCheck shell extension:
