WebAnswer (1 of 3): Cipher is a term in cryptography, and is not specific to computer hacking. It is another name for an encryption algorithm, which is a specific defined method to scramble data so that unauthorized people cannot read it. In a pure mathematical attack, (i.e., lacking any other information to help break a cipher) two factors above all count: • Computational power available, i.e., the computing power which can be brought to bear on the problem. It is important to note that average performance/capacity of a single computer is not the only factor to consider. An adversary can use multiple computers at once, for instance, to increa…
