In asymmetric cryptography, each user has two keys: a public key and a private key. The public key is shared with everyone, while the private key is kept secret. To encrypt a message, the sender uses the recipient&#8217;s public key. The recipient can then decrypt the message using their private key. This type of cryptography is more secure than symmetric cryptography, which uses the same key for both encryption and decryption.<\/p>\n<p>Public key cryptography is used in a variety of applications, including secure email, digital signatures, and online banking.
