Best Real-Life Math! RSA Encryption - All the math you need to encrypt data

By Daniel

Where do we use school mathematics in real life?

The following complete guide sets out ALL the mathematics we do in middle and early high school used in the RSA Public Key Cryptosystem.

RSA Encryption is one of the most modern and powerful methods of encryption and is used by computer scientists, big banks and websites who need to secure data.

Do not be surprised, the list is complete and no other, more complicated mathematics is ever used in RSA Encryption.
Topics done in grade school: Factors, Multiples, Products, Times Tables, Division, Remainders, Integers, Prime Numbers, Composite Numbers, Exponents, Rules for Divisibility etc.

Topics not specifically done in grade school but for which 7th-10th grade students possess ALL the mathematics knowledge: Modular Arithmetic, Successive Squaring, The Euclidean Algorithm, The Euler Phi Function, Euler's Formula, The Extended Euclidean Algorithm

It is important that students know (and that teachers always remind them) when they are busy with these topics, that they are learning fundamental mathematics needed to encrypt data and secret messages.

If you need the Tasks and Keys on All the Math needed for the RSA encryption, this is all of it, in A BUNDLE! Get it here:
