Webb1 mars 2024 · The created public key could not be used to infer the private key. In other words, the creation of the public key from the private key is a one-way process. This is the concept on which the security of public-key cryptography relies. The public-key algorithm not only performs encryption, but also provides authentication functionality. Webbprivate 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.
