Public key cryptography (PKC), also known as asymmetric cryptography, is a framework that uses both a private and a public key, as opposed to the single key used in symmetric cryptography. The use of key pairs gives PKC a unique set of characteristics and capabilities that can be utilized to solve challenges inherent in other cryptographic techniques. This form of cryptography has become an important element of modern computer security, as well as a critical component of the growing cryptocurrency ecosystem.
