RSA is the most widely studied of the public key algorithm, from the nearly two decades now, we have tested a variety of attacks, people gradually accepted, widely considered the best of the current public key, one of the options. The security of RSA relies on the factorization of large numbers, but in theory there is no proof of the difficulty of deciphering the RSA and the decomposition of large numbers equivalent difficulty. RSA' s major flaws that can not grasp it from the theory of how the confidentiality of the performance, but most scholars tended password factorization problem is not a NPC.
