WebJun 11, 2024 · Continuing with the simple example above, the private key of Site B is made from its public key as follows. private decrypt exponent = (public encrypt exponent) -1 Mod f (n) ∵ public encrypt exponent = 7 , and f (n) = 40. ∴ (private decrypt exponent x 7) Mod 40 = 1. ∴ private decrypt exponent = 23. WebJun 11, 2012 · Cryptography is a science that applies complex mathematics and logic to design strong encryption methods. Achieving strong encryption, the hiding of data’s meaning, also requires intuitive leaps that allow creative application of known or new methods. So cryptography is also an art.
