What (who) is Public-key cryptography - definition
Public-key cryptography

Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys. Each pair consists of a public key (which may be known to others) and a private key (which may not be known by anyone except the owner).

<cryptography> A piece of data used in {private-key
cryptography} and public-key cryptography. In the former
the private key is known by both sender and recipient whereas
in the latter it is known only to the sender.

Examples of use of Public-key cryptography
1. Cheman calls his encryption method «Absolute Public Key Cryptography.» The above security essential is seriously lacking in the encryption techniques presently available in the market.
