The basic idea is that an individual who wants to send a private message must first encrypt the message with the receiver's public key. WebHow to find a modular inverse. A naive method of finding a modular inverse for A (mod C) is: step 1. Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant. black and hot pink suits

"WebOct 4, 2015 · In textbook RSA, the Euler φ function φ(pq) = (p − 1)(q − 1) is used to define the private exponent d. On the other hand, real-world cryptographic specifications require the Carmichael lcm function λ(pq) = lcm(p − 1, q − 1) to define d´ . It is clear that the d´ divides d, and therefore using d´ may be more efficient than using d. " - Phi in cryptography
