Cryptography and Hashing Fundamentals in Python and Java

Description

In this course you will learn about cryptography and hashing in Python and Java as well. You will understand most of the private key (symmetric) and pubic key (asymmetric) cryptosystems on a step by step basis. You can learn about the theory as well as the implementation for every cryptographic algorithm – and how to crack these systems (so what are the weaknesses).

Chapter 1 – Cryptography Fundamentals

  • what is the aim of cryptography?
  • private key and public key cryptosystems

Chapter 2 – Caesar Cipher

  • Caesar cipher theory and implementation
  • how to crack Caesar cipher
  • frequency analysis and language detection

Chapter 3 – Vigenere Cipher

  • Vigenere cipher theory and implementation
  • how to crack Vigenere cipher with Kasiski-algorithm

Chapter 4 – One Time Pad (Vernam Cipher)

  • random and pseudo-random numbers
  • the XOR logical operator
  • one time pad theory and implementation
  • why is it impossible to crack Vernam cipher?
  • Shannon’s secrecy

Chapter 5 – Data Encryption Standard (DES)

  • data encryption standard (DES) theory and implementation
  • cryptoanalysis techniques
  • linear cryptoanalysis and differential cryptoanalysis

Chapter 6 – Advanced Encryption Standard (AES)

  • advanced encryption standard (AES) theory and implementation
  • Shannon’s confusion and diffusion

Chapter 7 – Asymmetric Cryptosystems

  • problems with private key cryptosystems
  • random numbers and prime numbers in cryptography

Chapter 8 – Modular Arithmetic

  • RSA algorithm theory and implementation
  • the problem of factorization

Chapter 11 – Advanced Modular Arithmetic

  • Euclidean and the greatest common divisor (GCD) problem
  • extended Euclidean algorithm (EGCD)
  • modular inverse problem

Chapter 12 – Elliptic Curve Cryptography (ECC)
