C839 Introduction to Cryptography| WGU C839| 130 QUESTIONS| WITH COMPLETE SOLUTIONS A typical use is digital signatures. One way. You cannot "un-hash" something. Collision resistant. SAM file - ANS-File in the Windows System directory where hashed passwords are stored. salt - ANS-random bits that are used as one of the inputs to the hash. MD5 - ANS-128 bit hash, specified by RFC 1321 not collision resistant. Flaw found in 1996 MD6 - ANS-Uses a Merkle Tree-like structure to allo...

Algorithm efficiency typically measured by the algorithm's computational complexity Computational complexity the amount of resources used by the algorithm. The most common resources considered are the runtime and memory usage. runtime complexity a function, T(N), that represents the number of constant time operations performed by the algorithm on an input of size N Space-complexity (of an algorithm) a function, S(N), that represents the number of fixed-size memory units...
