Yes. The certification key is used when signing (more properly, "certifying") other people's public keys. A signing key can be used for signing files or messages but the certification key is used for signing other people's keys. In short, it's the "primary" key. > Can that be changed without losing signatures on the public key? If > so, then the size of that can be increased slowly when needed. Unfortunately not. It is the primary key and its properties (e.g. key length) cannot be changed.
