Cryptography public key
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. … See more 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 … See more The most obvious application of a public key encryption system is for encrypting communication to provide confidentiality – a message that a … See more Examples of well-regarded asymmetric key techniques for varied purposes include: • Diffie–Hellman key exchange protocol • DSS (Digital Signature Standard), which incorporates the Digital Signature Algorithm See more • Oral history interview with Martin Hellman, Charles Babbage Institute, University of Minnesota.

One is used for encryption, while the other key can decrypts the message. Unlike symmetric cryptography, if one key is used to encrypt, that same key cannot decrypt the message, rather the other key shall be used.
