WebMar 16, 2024 · For the message encryption itself a symmetric cipher is used and for the key, the asymmetric one. Therefore, the slower, asymmetric method is used only for the key. So, faster symmetric data encrypts and decrypts the data. Thus, the whole process is more efficient especially for large amounts of data. 4.1. WebExamples: AES DES Caesar Cipher Public 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.
