What is the goal of cryptanalysis?

A.
To determine the strength of an algorithm

B.
To increase the substitution functions in a cryptographic algorithm

C.
To decrease the transposition functions in a cryptographic algorithm

D.
To determine the permutations used

Explanation:
Cryptanalysis is the process of trying to reverse-engineer a
cryptosystem with the goal of uncovering the key that was used. Once this key is
uncovered all other messages encrypted with this key can be accessed. Cryptanalysis
is carried out by the white hats to test the strength of the algorithm.
