WebApr 21, 2024 · Cryptography is a form of securing digital data and messages often using special keys that only the sender and recipient have access to. Cryptography uses mathematical systems and algorithms to encrypt and decrypt data. Symmetrical cryptography uses the same key for both encryption and decryption. WebMay 1, 2024 · For example: Bob and Alice agree on two numbers, a large prime, p = 29, and base g = 5 Now Bob picks a secret number, x (x = 4) and does the following: X = g^x % p (in this case % indicates the remainder. For example 3%2 is 3/2, where the remainder is 1). X = 5 ^4 % 29 = 625 % 29 = 16
