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 ... WebIn cryptography, a shared secret is a piece of data, known only to the parties involved, in a secure communication. This usually refers to the key of a symmetric cryptosystem. The shared secret can be a password, a passphrase, a big number, or an array of randomly chosen bytes. The shared secret is either shared beforehand between the ...
