Powershell write to variable instead of file

Question

I'm trying to use Azure powershell to pull an SSH key and add it to a VM. The cmdlet is

Get-AzKeyVaultKey... -OutFile filename

I'd like to avoid actually writing the key to the disk, but I need it in a variable. Is there any way to provide a variable acting like a file or something so I can go

-OutFile $someVariablePretendingToBeFile

and use that variable please?

The variable that is returned by Get-AzKeyVaultKey is of type PsKeyVaultKey if I get its key property, and call ToRSA() I get an RSACryptoServiceProvider But I still don't see where to get the public key string from! It's annoying b/c -OutFile produces exactly the public key

Thanks

Answer 1

Since Get-AzKeyVaultKey is not providing a way of doing (that I know of), can you get it to work with a simple:

$key=(Get-AzKeyVaultKey XXX)

To get the result in a variable?

Let us know !

Answer 2

Not sure if tis would work, it is a variant of the answer above. I can't test it just now

$PublicKey = Get-AzKeyVaultKey -VaultName $vaultName -KeyName $keyName
