Webb17 sep. 2024 · All cryptographic systems have at least one key. Symmetric encryption uses the same key to encrypt and decrypt, and asymmetric encryption uses two keys, one to encrypt and another to decrypt.

WebbDiffie–Hellman key exchange. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's public keys, Alice and Bob can compute a shared secret offline. The shared secret can be used, for instance, as the key for a symmetric cipher.
