WebFeb 11, 2024 · Asymmetric cryptography, or public key cryptography, solves the key distribution problem of symmetric key cryptography. It does so by using a pair of keys instead of a single one. An asymmetric key algorithm is used to generate a pair of keys: A private key and a public key. WebCryptography studies techniques aimed at securing communication in the presence of adversaries. While encryption is probably the most prominent example of a crypto- graphic problem, modern cryptography is much more than that.
