why is Powershell Get-FileHash sha256 value differernt from 7Zip's sha256 value

Question

Hi

I use powershell get-filehash sha256 to calculate a hash value on a file that has a file path greater than 260 characters long (includes file name). I get a value.

I copy the file to a file path with a short (less than 100 characters long) and use powershell's get-filehash and get the same sha256 value.

I use 7-Zip and replicate the steps on the same files. Both 7-Zip's sha256 values match.

The sha256 values from powershell get-filehash and 7-zip crc sha256 do not match.

does anybody know why?

thanks in advance

Hi,

The Get-FileHash cmdlet and 7-Zip calculate the same hash value on my Windows 10. Have your files been modified? The version of my 7-Zip is 23.01.
