One of the most well known encryptions today is the RSA encryption. This form for encryption uses asymmetric keys. This means that you cannot evaluate the second key if you have the first one and vice versa. The RSA encryption is a public-key crypto system, which uses two algorithms (E, D), one for encryption and one for …
