Given two numbers, a (the dividend) and n (the divisor), a modulo n (abbreviated as a mod n) is the remainder from the division of a by n. Lemma 3 in this post guarantees that d exists and is unique (and also explains what a modular multiplicative inverse is). Expressed mathematically, we need to find a number d such that: 11 × d = 1 + n(288) Using trial and error, we find that 131 works because 11 × 131 = 1 + 5(288). The algorithm capitalizes on the fact that there is no efficient way to factor very large (100-200 digit) numbers. Lets start by extracting n and e from the public key. RSA and Factoring: We do not know if RSA is as hard as factoring. CONJECTURE 6. The parts of the key should each be a single hex number, while the cryptotext should be a sequence of bytes. You need to enable JavaScript to run this app. Digital Signatures In the non-digital world, Alice would sign the document. Instead of computing c d (mod n), Alice first chooses a secret random value r and computes (r e c) d (mod n). How long time it will take depends on file size, your own download speed and the server's upload speed. Bob will send or give the encrypted message to Alice. Q = n(e-) × F Q = 2. Arithmetic sequences are very helpful to identify because the formula for the nth term of an arithmetic sequence is always the same: a n = a 1 + (n - 1)d. it is always easy to calculate n; given n, it is very difficult to compute pand q. Interestingly, though n is part of the public key, difficulty in factorizing a large prime number ensures that attacker cannot find in finite time the two primes (p & q) used to obtain n.
