### Classical Cryptosystems and Core Concepts

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.

### Mathematical Foundations for Cryptography

Welcome to Course 2 of Introduction to Applied Cryptography. In this course, you will be introduced to basic mathematical principles and functions that form the foundation for cryptographic and cryptanalysis methods. These principles and functions will be helpful in understanding symmetric and asymmetric cryptographic methods examined in Course 3 and Course 4. These topics should prove especially useful to you if you are new to cybersecurity. It is recommended that you have a basic knowledge of computer science and basic math skills such as algebra and probability.

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

Would have absorbed the course material more concretely if the instructor had slowed down on the pace at which concepts were being disseminated.

Very difficult course if you have no previous experience with cryptoanalysis and recent stats, but good because it makes you think!

Excellent lectures. Mostly very easy to follow, but some mathematical points were ran through a bit too quickly and thinly.

The lectures were educational, and interesting without speaking down to you. I learned a lot without being overwhelmed

Some annoying errors in quizes, and I wish there was something more about elliptic curves, but otherwise good course.

Thank you for taking the time to upload your videos. I hope you create a capstone course.

Good course, but would like some more exercises to implement the mathematics learnt.
