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. Webcryptography, a central problem is to guarantee that a particular public-key is authentic and valid. The traditional approach to this problem is through public-key certificates emitted by a Public Key Infrastructure (PKI), in which a Certificate Authority (CA) certifies ownership and validity of public-key certificates.
