Find the secret key d in RSA if n=1147 and e=7. Find c if m=64. How to extract m from the output?

Decrypt 74: 𝐶 ′ = 74 ⋅ 7   ( mod  59 ) = 518   ( mod  59 ) = 46 C ′ =74⋅7 (mod 59)=518 (mod 59)=46 Using the superincreasing sequence ( 2 , 3 , 7 , 15 , 29 ) (2,3,7,15,29): 46 − 29 = 17 17 − 15 = 2 46−29=17 17−15=2

Encrypt and decrypt by means of the RSA algorithm with the following system parameters:1. p = 3, q = 11, d = 7, x = 52. p = 5, q = 11, e = 3, x = 9

Creating a private key. (a) To create the private key, we need one extra positive integer, d. Find a value of d such that ed ≡ 1 (mod ϕ(n)). Note that e and d are allowed to be the same number (if this condition is satisfied). For the sake of making the calculations easier, you must pick a value of d that is single-digit. You might find that your choice for e from Part 1 does not produce a value of d that is single-digit. In that case, try selecting a different value for e. A bit of exploration (or coding) should give you a single-digit choice for both e and d with any of the prime pairs available to you in this assignment. The ordered pair (d, n) is your private key. You should keep this information to yourself, as it can be used to decode any message coded using your public key.
