WebMay 1, 2024 · Public key cryptography (PKC) is an encryption technique that uses a paired public and private key (or asymmetric key) algorithm for secure data communication. A message sender uses a recipient's public key to encrypt a message. To decrypt the sender's message, only the recipient's private key may be used. Advertisements WebAsymmetric cryptography is a second form of cryptography. Asymmetric cryptography is scalable for use in very large and ever expanding environments where data are frequently exchanged between different communication partners.
