I used this method to create a public key in a different section of my program at a different time.

 publicKey = pivSession.GenerateKeyPair(
     PivSlot.Authentication,
     PivAlgorithm.Rsa2048,
     PivPinPolicy.Never,
     PivTouchPolicy.Never);

now I would like to read my old familiar public key again.

I thought, I could recreate my public key by accessing the slot, where the private key has been stored.

var x = pivSession.GetMetadata(PivSlot.Authentication).PublicKey;

Is this a correct approach???
Should I use a different slot on the Yubikey?
