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 Fundamentalswhat is the aim of cryptography?private key and public key cryptosystemsChapter 2 - Caesar CipherCaesar cipher theory and implementationhow to crack Caesar cipherfrequency analysis and language detectionChapter 3 - Vigenere CipherVigenere cipher theory and implementationhow to crack Vigenere cipher with Kasiski-algorithmChapter 4 - One Time Pad (Vernam Cipher)random and pseudo-random numbersthe XOR logical operatorone time pad theory and implementationwhy is it impossible to crack Vernam cipher?Shannon's secrecyChapter 5 - Data Encryption Standard (DES)data encryption standard (DES) theory and implementationcryptoanalysis techniqueslinear cryptoanalysis and differential cryptoanalysisChapter 6 - Advanced Encryption Standard (AES)advanced encryption standard (AES) theory and implementationShannon's confusion and diffusionChapter 7 - Asymmetric Cryptosystemsproblems with private key cryptosystemsrandom numbers and prime numbers in cryptographyChapter 8 - Modular Arithmeticmodular arithmetic fundamentalsfinding prime numbers - naive approach and advanced algorithmsinteger factorization problemdiscrete logarithm problemChapter 9 - Diffie-Hellman Key ExchangeDiffie-Hellman key exchange algorithm theory and implementationprime numbers and primitive rootsman-in-the-middle attackChapter 10 - RSA AlgorithmRSA algorithm theory and implementationthe problem of factorizationChapter 11 - Advanced Modular ArithmeticEuclidean and the greatest common divisor (GCD) problemextended Euclidean algorithm (EGCD)modular inverse problemChapter 12 - Elliptic Curve Cryptography (ECC)elliptic curve cryptography theory and implementationwhy does Bitcoin use elliptic curve cryptography?
