The RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptographic system, a suite of cryptographic algorithms used for private security services or purposes, and this allows public key encryption, widely used to secure particularly sensitive data sent over an insecure network s...
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...

Quantum algorithms, for instance Shor's algorithm, can quickly factor large numbers, thus making RSA obsolete. Against traditional attacks, with large keys (2048 bit or more) RSA is secure. However, advancement in computing powers may prove to be a challenge to RSA's reliability in the future...
