Suppress console output in PowerShell

I have a call to GPG in the following way in a PowerShell script: 

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose > $null

I don't want any output from GPG to be seen on the main console when I'm running the script.

Due to my noobness in PowerShell, I don't know how to do this. I searched Stack Overflow and googled for a way to do it, found a lot of ways to do it, but non of it worked.

The "> $null" for example has no effect. I found the --quiet --no-verbose options for GPG to put less output in the console, still it's not completely quiet, and I'm sure there is a way in PowerShell too.

Try redirecting the output to Out-Null. Like so:

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.
