RSA algorithm is the most popular asymmetric key cryptographic algorithm based on the mathematical fact that it is easy to find and multiply large prime numbers but difficult to factor their product. It uses both private and public key (Keys should be very large prime numbers). Mathematical resea...
Alice generates her RSA keys by selecting two primes: p=11 and q=13. The modulus is n=p×q=143. The totient is n ϕ(n)=(p−1)x(q−1)=120. She chooses 7 for her RSA public key e and calculates her RSA private key using the Extended Euclidean algorithm, which gives her 1...
RSA Encrypt and Decrypt - ExampleLet examine oneexample of RSA encryption and decryption, along with the calculations, following the above formulas. Assume we have generated the RSA public-private key pair:modulusn= 143public exponente= 7private exponentd= 103public key = {n,e} = {143, 7}p...

RSA, a popular encryption algorithm since 1977, employs public and private key pairs. While suitable for various tasks, RSA's complexity limits its use for encrypting large data. Instead, RSA excels in creating digital signatures and certificates, ensuring secure authentication, communication, and ...

the sender starts by generating a hash value of the message using a cryptographic hash function. Then, you sign it by applying the RSA algorithm using the private key, which generates the digital signature as the output. The recipient can then apply the RSA algorithm to the digital signature ...
