PKI multiple public keys

Question

I\'m wondering if I can have multiple public keys for a private key.

Can this be done? If so, what are the security issues!?

If I generate multiple key pairs

Answer 1

Private/Public keys have a 1-1 relationship, and so it's not possible to have more than one public key for a given private key.

However, you can have 3 separate certificates for the same public key, if that's the type of thing you're looking for.
