These keys are separate yet mathematically related to each other. That’s because they’re generated using an asymmetric algorithm that binds the public key to the private one.
WebIt is to one's benefit to use asymmetric encryption techniques, such as those utilized in public-key cryptography. This is the case, for instance, with [c]cryptography that relies on shared public keys. Using public-key cryptography or another kind of asymmetric encryption is a good idea. One such use is public-key cryptography.
