The RSA Public Key Cryptosystem is one of the best and widely used cryptosystems in the world today. Some people can talk a little about some of what RSA Encryption entails, but very few people can actually encrypt (and decrypt) data from start to finish using the RSA Public Key Cryptosystem.

Other topics covered during the course: Number Theory, Multiples, Factors, Products, Modular Arithmetic, Divisibility of Integers, Prime Numbers, Prime Factorization, Exponents, Exponential Laws, Binary Expansion of Integers, The Euler Phi Function, Euler's Formula, Fermat's Little Theorem, The Euclidean Algorithm, The Extended Euclidean Algorithm, Relative Prime Pairs of Integers, Encryption of secret messages, Decryption of secret messages, Shift Cypher, Successive Squaring, Middle School Mathematics, High School Mathematics, Pre-Algebra, Algebra I, Algebra II, Real-life Mathematics.

After this course you will know exactly how to encrypt and decrypt data using the RSA Public Key Cryptosystem. In seven video lessons you will become familiar with all the mathematics that is needed. In the last two videos you will learn exactly how to put that knowledge together to encrypt (lesson 8) and decrypt (lesson 9) data.

The level of mathematics involved is going to be a pleasant surprise. As an experienced middle and high school mathematics teacher I can tell you with confidence that by the time you were done with 10th grade, you knew (or should have known) all the math in this course.

Who would ever wonder where the mathematics they took in Middle and High School ever gets used in real life?

I tried to be thorough but managed to keep the course short. Iknow you do not have much time to watch videos and I do not have much time to make videos. The average length of the videos is under 10 minutes and the worksheets should never take you more than 20 or 30 minutes.

Who knows what new horizons you will see or what doors might open up for you after this course. I am excited for you.
