WebIn cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Symmetric key encryption, also called secret key encryption, depends on the use of ciphers, which operate symmetrically. WebStep 3: Encryption. The sending computer encrypts the secret data using the receiving computer's public key and a mathematical operation. The power of public key encryption is in that mathematical operation. It's a "one-way function", which means it's incredibly difficult for a computer to reverse the operation and discover the original data.
