Webprivate key (secret key): In cryptography , a private key (secret key) is a variable that is used with an algorithm to encrypt and decrypt code. Quality encryption always follows a fundamental rule: the algorithm doesn't need to be kept secret, but the key does. Private keys play important roles in both symmetric and asymmetric cryptography. WebNov 27, 2024 · A private key that is accessed by anyone other than its owner is considered “compromised”. Public key: a key that can be shared with anyone. The public key in a private/public pair is the only key that can be used to decrypt data that was encrypted by the private key. The “PK” in “PKI” comes from its usage of public keys. uob changi airport branch
