Win10 - How to pipe the output from one command as an argument of another to check file hash?

Question

Lets say that I need to verify the md5 hash of a file against the hash provided by the website.

I use certutil -hashfile .\amazon-corretto-11.0.10.9.1-windows-x64.msi md5 or Get-FileHash -Path .\amazon-corretto-11.0.10.9.1-windows-x64.msi -Algorithm md5 in powershell to get the hash, then I look at the hash from the download website, and compare them letter by letter. Is there a way to let the command line do the comparison?

I tried certutil -hashfile .\amazon-corretto-11.0.10.9.1-windows-x64.msi md5 | echo == "website_hash", but it didn't work.

Solutions in command line and powershell are both welcomed.

Continuing from my comment. Try this:

Get-FileHash -Path 'D:\temp\book1.txt' -Algorithm MD5 | 
Format-Table -AutoSize
# Results
<#
Algorithm Hash                             Path             
--------- ----                             ----             
MD5       D572724F26BD600773F708AB264BE45B D:\temp\book1.txt
#>


$CompareObjectSplat = @{
    DifferenceObject = (Get-FileHash -Path 'D:\temp\book1.txt' -Algorithm MD5).Hash
    ReferenceObject  = (Get-FileHash -Path 'D:\temp\book1.txt' -Algorithm MD5).Hash
}
Compare-Object @compareObjectSplat -IncludeEqual
