Key encryption technologies are used to encrypt and decrypt data. A key is a value that is used with cryptographic algorithms to encrypt some input (called plaintext). The output is called ciphertext. Given the same input and the same algorithm, a different key will produce different ciphertext. See "Cryptography," "Public-Key Cryptography," and "PKI (Public-Key Infrastructure)."
