Should I be worried? (sha256 hash not matching)

[storkinsj]

Hi All,
Picture paints a thousand words. Why don't these match?

Why don't these match?

The hash 53749fccea499de58d7c5de0c38af705c36743f50d7d7510c5b5d17df21de96a for the GT-AX11000_388.1_0_ubi.w firmware file matched for me using the MD5 & SHA Checksum Utility 2.1 program on Windows 10. Maybe try redownloading the firmware file again if you haven't done so already.

You’re hashing the filename only, not the file content.

rtradmin@router:/tmp/home/root# echo -n GT-AX11000_388.1_0_ubi.w | sha256sum

@dave14305 is right, you shouldn't be using pipes.


Also the sha256sum command doesn't work on all routers, it's only available in newer models, so for anyone reading this thread, you can use the following command to get the sha256 hash on any Merlin/Asus router via openssl.

openssl sha256 "/path/yourffile"

If you want to output only sha256:

openssl sha256 "/path/yourffile" | awk '{print $2}'

It even works well on macOS and most linux distributions.

If you insist on using sha256sum, then please use it like this:

sha256sum "/path/yourffile"

For Windows command line:

CertUtil -hashfile "C:\path\yourfile" SHA256

For Windows powershell:

Get-FileHash "C:\path\yourfile"
