Two encryption exponents
WebLet N = pq be the product of two large primes of the same size (n/2 bits each). As [1] explains, a typical size for N is n=1024 bits, i.e. 309 decimal digits. Let e, d be two integers satisfying ed = 1 mod φ(N) where φ(N) = (p-1) (q-1). N is called the RSA modulus, e is called the encryption exponent, and d is called the decryption exponent. WebJul 8, 2010 · 1 Answer. You can use the extended Euclidean algorithm to solve for d in the congruence. For RSA encryption, e is the encryption key, d is the decryption key, and …
