Cryptography and public key infrastructure

WebPublic Key Cryptography, or asymmetric cryptography, uses two keys to encrypt data. One is used for encryption, while the other key can decrypts the message. Unlike symmetric cryptography, if one key is used to encrypt, that same key cannot decrypt the message, rather the other key shall be used. WebJul 30, 2024 · Public key encryption enables users to secretly send and receive messages. It allows each user to create a pair of keys: a public key and a private key. Both keys have a mathematical relation between them. But a private key cannot be practically derived from a public key. In encryption, one can use a public key to encrypt a message, which the ...
