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… Webasymmetric-key cryptography. Also called public-key cryptography. The use of different but mathematically related keys to encrypt and to decrypt content. One of the keys is public and is typically made available in an X.509 version 3 certificate. The other key is private and is stored securely.
