WebContrarily, in an asymmetric encryption algorithm, also known as public-key encryption, there exist two keys: one is public and can only be used for encrypting data, whereas the other one remains private and is used only for decrypting ciphertexts. Does HTTPS use symmetric or asymmetric cryptography? 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.
