WebApr 11, 2024 · A private key is a cryptographic key used in an encryption algorithm to both encrypt and decrypt data. These keys are used in both public and private encryption: In private key encryption, also known as symmetric encryption, the data is first encrypted using the private key and then decrypted using the same key. WebA traditional way to achieve authenticity is to use Message Authentication Code (MAC): H K ( D) = T, where T is called tag .
