What cryptography method secures communications on the Internet by using two different keys for encryption and decryption?

Asymmetric Cryptography

Asymmetric cryptography, also known as public key cryptography, has revolutionized security on the Internet. Introduced in the 1970s, this method uses a pair of keys – one public and one private – to encrypt and decrypt messages. The major advantage of this approach is that even if the public key is known to everyone, only the holders of the corresponding private key can decrypt the messages. This has enabled secure online transactions, from banking to e-commerce, thereby transforming the global economy by making electronic commerce both convenient and safe.
