Crypto public key

WebThe cryptographic system used with PKI, known as public-key cryptography, protects data in motion by ensuring that it is digitally signed before being transmitted over networks such as the Internet and other public communications systems. PKI is sometimes referred to as private key infrastructure or private key encryption; however, no such ... Before the mid-1970s, all cipher systems used symmetric key algorithms, in which the same cryptographic key is used with the underlying algorithm by both the sender and the recipient, who must both keep it secret. Of necessity, the key in every such system had to be exchanged between the communicating parties in some secure way prior to any use of the system – for instance, via a secure channel. This requirement is never trivial and very rapidly becomes unmanageable as th…
