Strong skills in mathematics (especially number theory, probability, and algebra), logic, pattern recognition, computer science, and sometimes linguistics are essential for modern cryptoanalysis.
No. While historically associated with intelligence, it is now widely used in academia for research, by cybersecurity professionals to test the strength of encryption products, and by companies to audit their own security.
