Websharpen the understanding of a speci c problem and advance the evolution of cryptography in general. SAT solvers have been shown to be a powerful tool in testing mathematical assumptions. In this paper, we extend SAT solvers to better work in the environment of cryptography. Previous work on solving cryptographic problems with SAT solvers has ... 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.
