The public key must be [[exchanged]]. A mathmatical operation then encrypts the message with the public key of the receiver. Mostly the [[RSA]] [[Algorythm]] is used here. As it is based on not-solveable complex mathematical operations, the encryption might be regarded as safe. But what happens if the complex problem is soon a simple one? Better to not have only [[RSA]] as the only method in this regard, but also here some alternatives: e.g. [[ElGamal]] or [[NTRU]]. [[NTRU]] is regarded as secure even for [[quantumcomputing]].</div></td></tr>
