WebIn public-key encryption schemes, the encryption key is published for anyone to use and encrypt messages. However, only the receiving party has access to the decryption key that enables messages to be read. Public-key encryption was first described in a secret document in 1973; beforehand, all encryption schemes were symmetric-key (also called ... WebIt must be computationally infeasible to determine the private key if the only thing one knows is the public key. Therefore, the public key can be distributed publicly while the private key is kept secret and secure. Together the keys are referred to as a key pair. Another more common name for asymmetric encryption is public-key cryptography ...
