Select e: gcd(e,160)=1; choose e =7 5. How can i give these numbers as input.


• Solution: • The value of n = p*q = 13*19 = 247 • (p-1)*(q-1) = 12*18 = 216 • Choose the encryption key e = 11, Calculate F (n): F (n): = (p-1)(q-1) = 4 * 6 = 24 Choose e & d: d & n must be relatively prime (i.e., gcd(d,n) = 1), and e & d must be multiplicative inverses mod F (n). No provisions are made for high precision arithmetic, nor have the algorithms been encoded for efficiency when dealing with large numbers. What is the encryption of the message M = 41? This is an alternate ISBN. RSA Example (1) • p = 17, q = 11, n = 187, Φ(n) = 160 • Let us choose e=7, since gcd (7,160)=1 • Let us compute d: de=1 mod 160, d=23 (in fact, 23x7=161 = 1 mod 160 • Public key = …

Publish public key KU={7,187} 7.

”: • Substitute the value of “” Answer: n = p * q = 7 * 11 = 77 . <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 16 0 R 19 0 R 22 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>

With the above background, we have enough tools to describe RSA and show how it works. - Definition & Types, What is a Motherboard? endobj Initially need to calculate the value of “”: • Substitute the value of “p” as “17” and “q” as “23” in the answer!

Determine d: d.e= 1 mod 160 and d < 160 Value is d=23 since 23x7=161= 1x160+1 6. <>>> RSA algorithm is an asymmetric cryptography algorithm which means, there should be two keys involve while communicating, i.e., public key and private key. What is the encryption of the message M = 41?
It is based on the principle that it is easy to multiply large numbers, but factoring large numbers is very difficult. Choose n: Start with two prime numbers, p and q.

The modern computers use the RSA algorithm to encrypt and decrypt the data, it is the concept of cryptography, It is an asymmetric algorithm, RSA algorithm consists of two keys are private key and public keys and p,q initial prime nos and totient phi(n)=(p-1)*(q-1). p =17, q = 11 n = 187, e= 7 & d = 23 After sufring on internet i found this command to generate the public,private key pair : openssl genrsa -out mykey.pem 1024. %���� {/eq} q.
