Commercial reasons alone (e.g., e-commerce, online access to proprietary databases from web browsers) were sufficient. For example, the RSA 2048 algorithm generates two random prime numbers that are each 1024 bits in length. For an enterprise, PKI authentication can make the difference between an intruder gaining access to the network through a connected device and keeping a potentially dangerous threat away from the organization. Examples of implementations of this approach are PGP (Pretty Good Privacy) and GnuPG (an implementation of OpenPGP, the standardized specification of PGP). The most distinct feature of Public Key Infrastructure (PKI) is that it uses a pair of keys to achieve the underlying security service. If someone compromises the channel that shares the key, the system can be broken. Confidentiality: Assurance that no entity can maliciously or unwittingly view a payload in clear text.
