Intelligence. It's the ability to think abstractly. Challenge the unknown. Solve the impossible. NSA employees work on some of the world's most demanding and exhilarating high-tech engineering challenges. Applying complex algorithms and expressing difficult cryptographic problems in terms of mathematics is part of the work NSA employees do every day.Today I solved the Crypto Challenge of week 15. It took me a total of 2 hours and 13 minutes to finish. First, I tried to find common 2 letter words.Searching for 2 letter words!After that, I found the word mathematics. I searched on google for mathematics in 1971 on which I found the following article: https://en.wikipedia.org/wiki/Association_for_Women_in_MathematicsFrom the start of this challenge, I was searching for a name consisting of 2 x 4 letter parts. Mary Gray was the best name I found in my criteria. I continued searching for Mary Gray and found that she had won awards in 2001 which matched up perfectly! After some more thorough searching and testing, I completed the challenge!A --> MB --> WC --> UD --> TF --> EH --> IJ --> RK --> AL --> NM --> DN --> PO --> LP --> YR --> HS --> OT --> CW --> SX --> GY --> FZ --> X
MARY GRAY, WHO FOUNDED THE ASSOCIATION FOR WOMEN IN MATHEMATICS IN 1971, WAS A 2001 RECIPIENT OF THE PRESIDENTIAL AWARDS FOR EXCELLENCE IN SCIENCE, MATHEMATICS AND ENGINEERING MENTORING PROGRAM.
