WebAbout encryption keys. The encryption keys that are used to encrypt data are described. An encryption key is typically a random string of bits generated specifically to scramble and unscramble data. Encryption keys are created with algorithms designed to ensure that each key is unique and unpredictable. The longer the key constructed this way ... Web22 feb. 2024 · In a PKE, one encrypts a message using the public key and decrypts using the private key. In a KEM, one uses the public key to create an “encapsulation” — giving a randomly chosen shared key — and one decrypts this “encapsulation” with the private key. The reason why KEMs exist is that PKE schemes are usually less efficient than ...
