À propos de ce cours : Welcome to Introduction to Applied Cryptography. Cryptography is an essential component of cybersecurity. The need to protect sensitive information and ensure the integrity of industrial control processes has placed a premium on cybersecurity skills in today’s information technology market. Demand for cybersecurity jobs is expected to rise 6 million globally by 2019, with a projected shortfall of 1.5 million, according to Symantec, the world’s largest security software vendor. According to Forbes, the cybersecurity market is expected to grow from $75 billion in 2015 to $170 billion by 2020. In this specialization, you will learn basic security issues in computer communications, classical cryptographic algorithms, symmetric-key cryptography, public-key cryptography, authentication, and digital signatures. These topics should prove especially useful to you if you are new to cybersecurity Course 1, Classical Cryptosystems, introduces you to basic concepts and terminology related to cryptography and cryptanalysis. It is recommended that you have a basic knowledge of computer science and basic math skills such as algebra and probability.
Les destinataires de ce cours : Learners with CS experience or education looking to: ○ Enhance/refresh critical skills; ○ Seeking to expand their opportunities. Learners undecided about pursuing a bachelor’s degree: ○ Seeking professional credit that may be applied towards a bachelor’s degree.

Cryptanalysis
Delving deeper into cryptanalysis, in this module we will discuss different types of attacks, explain frequency analysis and different use cases, explain the significance of polyalphabetical ciphers, and discuss the Vigenere Cipher. When you have completed this module, you will have an appreciation of the different types of attacks and under what kinds of situations each might be applicable.

It is a good course. I got few information about hash attack which I didn't know before. Only thing which I wish to have more is a little more hands on and also detailed example about Vigenere cipher
