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. WebA cryptographic hash function is a tool for turning arbitrary data into a fixed-length “fingerprint”. Hash functions are designed so that it is hard to find two different inputs that have the same fingerprint, and it is difficult to find a …
WebMar 21, 2013 · For many NP-complete problems, algorithms exist that solve all instances of interest (in a certain scenario) reasonably fast. In other words, for any fixed problem size (e.g. a given "key"), the problem is not necessarily hard just because it is NP-hard. NP-hardness only considers worst-case time.
