'''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'''.{{Ref RFC|4949|notes=no}}<ref>{{Cite journal |last1=Bernstein |first1=Daniel J. |last2=Lange |first2=Tanja |date=2017-09-14 |title=Post-quantum cryptography |url=http://www.nature.com/articles/nature23461 |journal=Nature |language=en |volume=549 |issue=7671 |pages=188–194 |doi=10.1038/nature23461 |pmid=28905891 |bibcode=2017Natur.549..188B |s2cid=4446249 |issn=0028-0836}}</ref> Key pairs are generated with [[cryptographic]] [[algorithms]] based on [[mathematical]] problems termed [[one-way function]]s. Security of public-key cryptography depends on keeping the private key secret; the public key can be openly distributed without compromising security.<ref>{{Cite book|url=https://books.google.com/books?id=Dam9zrViJjEC|title=Cryptography and Network Security: Principles and Practice|last=Stallings|first=William|date=3 May 1990|publisher=Prentice Hall|isbn=9780138690175|page=165|language=en}}</ref> There are many kinds of public-key cryptosystems, with different security goals, including [[digital signature]], [[Diffie–Hellman key exchange]], [[Key encapsulation mechanism|public-key key encapsulation]], and public-key encryption.
Public key algorithms are fundamental security primitives in modern [[cryptosystem]]s, including applications and protocols that offer assurance of the confidentiality and authenticity of electronic communications and data storage. They underpin numerous Internet standards, such as [[Transport Layer Security|Transport Layer Security (TLS)]], [[SSH]],
