1. Create an RSA private key 2. Output the key in a text format so that it shows the following: modulus public exponent (e) private exponent (d) the primes (p and q) Send me a file called key.txt with this information. 3. Using openssl's rsautl option encrypt this message to me: "NAME" using the public key that's embedded with the private key above. Attach a file named encrypted.txt that contains the encrypted message. Hint: Copy the text above and put...
1.Which of the following statements about asymmetric-key encryption is correct? a When using asymmetric-key encryption method, a total of two keys are necessary in electronic communication between two parties. b Employees in the same company share the same public key. c Most companies would like to manage the private keys for their employees. d Most companies would like to use a Certificate Authority to manage the public keys of their employees. e Two of the above are correct. 2 Which...
Use C++ forehand e receiver creates a public key and a secret key as follows. Generate two distinct primes, p andq. Since they can be used to generate the secret key, they must be kept hidden. Let n-pg, phi(n) ((p-1)*(q-1) Select an integer e such that gcd(e, (p-100g-1))-1. The public key is the pair (e,n). This should be distributed widely. Compute d such that d-l(mod (p-1)(q-1). This can be done using the pulverizer. The secret key is the pair (d.n)....
Using RSA cipher, public key e=3, private key d=7 Encrypt the following message “Hello there” Decrypt the previous message
Question1: Alice and Bob use the Diffie–Hellman key exchange technique with a common prime q = 1 5 7 and a primitive root a = 5. a. If Alice has a private key XA = 15, find her public key YA. b. If Bob has a private key XB = 27, find his public key YB. c. What is the shared secret key between Alice and Bob? Question2: Alice and Bob use the Diffie-Hellman key exchange technique with a common...
p=3, q=7 Suppose that Bob wants to create an example of an RSA public-key cryptosystem by using the two primes p ??? and q ???. He chooses public encryption key e He was further supposed to compute the private decryption key d such that ed 1 mod A(pq)). However, he confuses A and and computes instead d' such that ed' =1 (mod P(pq)). (i) Prove that d' works as a decryption key, even though it is not necessarily the same...
The Diffie-Hellman public-key encryption algorithm is an alternative key exchange algorithm that is used by protocols such as IPSec for communicating parties to agree on a shared key. The DH algorithm makes use of a large prime number p and another large number, g that is less than p. Both p and g are made public (so that an attacker would know them). In DH, Alice and Bob each independently choose secret keys, ?? and ??, respectively. Alice then computes...
Using RSA algorithm, if p=3 and q=11, k=3, then the public key is equal to (You may use the formulas below): Select two large prime numbers P, 9 Compute n = pxq v = (p-1) (q-1) • Select small odd integer k relatively prime to v gcd(k, v) = 1 Compute d such that (d k)%v = (k d)%v = 1 Public key is (k, n) Private key is (d, n) . . . Select one: a. (3,11) b. (33,3)...
