Royal Apps

 in TSX 3.3.1 I load a RSA key into a credential (with or without passphrase. and i have tried one created on my mac, and on a linux machine). When i try and use that credential for a terminal session, I get "Load key "/Users/user/Library/Caches/com.lemonmojo.RoyalTSX.App/iTerm2Connection/TemporaryPrivateKey_3": invalid format"

Is that the correct way to handle that? Do i have some other thing going on?

Here's the error that is logged
