Usually a public SSH key is generated at the same time as a private key.
SSH keys are always generated in pairs with one known as the private key and the other as the public key. The private key is known only to you and it should be safely guarded. By contrast, the public key can be shared freely with any SSH server to which you wish to connect.
Unlike a private SSH key, it is acceptable to lose a public key as it can be generated again from a private key at any time.
