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. great white shark ancestorsWebThis cryptographic mechanism resolves the problem of adversaries altering messages by creating a MAC key that is shared by both the message originator and the recipient.
