WebJun 15, 2024 · As an example, let’s factor 1457 = 31 \times 47. We have \phi (1457) = 1380 = 2^2 \times 3 \times 5 \times 23; the part modulo 31 is crumbly, but 47 is twice a prime plus 1. The nontrivial square roots of 1 modulo 31 and 47, respectively, are, of course, 30 and 46. WebThe three types of cryptography are symmetric, asymmetric, and hash values. The many examples of cryptography are DES, AES, RSA, and Diffie-Hellman key exchange. Cryptography has some challenges, including weak keys, insider threats, and incorrect use of keys.
