 #### Cryptography Researcher
 
-Cryptography researchers create the mathematics or repurpose existing
-algorithms to craft the weapons or implements of change that the
-developers use.  They make use of advanced algebra to exploit the
-boundaries or hard limits set by the universe on reality to create
-cryptographic schemes that obey certain properties. They are in a
-sense reality-hackers. They hack reality to create systems that obey
-objective properties due to the underlying mathematics. Needless to
-say, the advanced cryptographer is a good mathematician.

 For cryptography, you will study ["Abstract Algebra"](https://agorism.dev/book/math/algebra/%28Dover%20Books%20on%20Mathematics%29%20Charles%20C%20Pinter%20-%20A%20Book%20of%20Abstract%20Algebra-Dover%20Publications%20%282010%29.pdf) by Pinter, and starting with simple cryptographic schemes
 gradually move towards learning more complex ones. You will prototype
