This is an implementation of Fermat's primality test in Python. The algorithm is polynomial in the size of the input and it works in O(k polylog(p)) where k is the test accuracy parameter and p is the candidate being tested.
Because Fermat's algorithm uses randomness, it is a probabilistic algorithm.
Fermat's test is a flawed algorithm because Carmichael numbers are composite numbers that the test thinks are prime.
Polynomial-time primality testing has many applications in cryptography such as key generation.

For an introduction to complexity and big-O, big-Ω notation see: https://dionyziz.com/complexity/
Soup's number theory book: http://www.shoup.net/ntb/ntb-v2.pdf
This is a classical number theory algorithm implementation in Python.
The Sieve of Eratosthenes and trial division are the simplest way of determining whether a number is a prime, a primality test. This is an exponential way of checking for primality, as the complexity is Ω(sqrt(n)).
Primality testing has many applications including cryptography.

In 1637, Pierre de Fermat claimed to have the proof to his famous conjecture, but, as the story goes, it was too large to write in the margin of his book. Yet even after Andrew Wiles’s proof more than 300 years later, we’re still left wondering: what proof did Fermat have in mind?
The mystery surrounding Fermat’s last theorem may have to do with the way we understand prime numbers. You all know what prime numbers are. An integer greater than 1 is called prime if it has exactly two factors: 1 and itself. In other words, p is prime if whenever you write p as a product of two integers, then one of those integers turns out to be 1. In fact, this definition works for negative integers, too. We simply incorporate -1. But the prime numbers satisfy another definition that maybe you haven’t thought about: An integer p is prime if, whenever p divides a product of two integers, then p divides at least one of those two integers.

Types of digital signature approaches
- RSA approach
- DSS approach
Digital Signature Algorithm with easy explanation.The Digital Signature Algorithm (DSA) is a Federal Information Processing Standard for digital signatures.It was proposed by the National Institute of Standards and Technology (NIST) in August 1991 for use in their Digital Signature Standard (DSS) and adopted as FIPS 186 in 1993.

Can a Neural Network accurately predict primality? Not Really!
Demo devoloped in VC++ 2017. Output NN learns fast ofc, because of the nature of the input to output.
Non linearity is not good NN material.

Fermat's Little Theorem was observed by Fermat and proven by Euler, who generalized the theorem significantly. This theorem aids in dividing extremely large numbers and can aid in testing numbers to see if they are prime. For more advanced students, this theorem can be easily proven using basic group theory.

In number theory, integer factorization or prime factorization is the decomposition of a composite number into smaller non-trivial divisors, which when multiplied together equal the original integer.
When the numbers are very large, no efficient, non-quantum integer factorization algorithm is known; an effort by several researchers concluded in 2009, factoring a 232-digit number (RSA-768), utilizing hundreds of machines over a span of two years. However, it has not been proven that no efficient algorithm exists. The presumed difficulty of this problem is at the heart of widely used algorithms in cryptography such as RSA. Many areas of mathematics and computer science have been brought to bear on the problem, including elliptic curves, algebraic number theory, and quantum computing.

Abstract: I will give an beginners' introduction to n-categories. First I'll explain roughly what an n-category is, and talk about some of the dreams that first led people to want to develop a theory of n-categories. Then I'll go into more detail, leading up to a description of the state of the art and of some of the difficulties involved in trying to make those dreams come true. This is a completely introductory talk, for those who know nothing about n-categories. Experts will be bored senseless.
