WebRSA problem. In cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key. The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the eth roots of an arbitrary number, modulo N. WebThanks to this exploration of the Caesar Cipher, we now understand the three key aspects of data encryption: Encryption: scrambling the data according to a secret key (in this case, the alphabet shift).
