About the Course

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....

Interesting course on an Interesting topic taken in a pleasant, enjoyable, and simple manner.

Never did I feel bored or out of my depth even though I am a stranger to the topic.

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

Really good start into the world of cryptography! However at times (especially at the hashing part) it gets really complex and you'll need to listen and read it multiple times, and find some simplified examples outside of the course to really understand what happening.

The content in the lectures is pretty good. I would've liked some better reading materials beyond Wikipedia, and the presenter was hard to listen to as a lecturer because he seemed to be just reading from a cue card. I learned stuff though.

Good for academic students since the course introduces lots of fancy terms. If you want to just learn about the cryptography, then this course is not for you. If you want to go deep into cryptography, then register for this one!

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

Introductional but very nice. Grading can maybe be bettered. Seems somehow to investigate if you have "followed" than if you have "understood" but not easy to do much better for an online course.

Great course!

But please add the translation into Russian. It is very difficult to understand technical English from a topic of cryptography that is unfamiliar to me, as a beginner.

I was expecting more of the mathematics behind Cryptography. Even though this course didn't provide that, it was good. A good introduction to the field of cryptography.

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

This course and the style of lecturing was nice but if there are more problem oriented type class is there then it would be more interesting

Could have been better if it the lectures could have been made more elaborate, also as a beginner it is hard to follow the terminology.

Although my head started spinning halfway through the course, it was filled with enough fascinating concepts to motivate me to finish.

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.

some concepts introduced in this course can be non trivial and vague which requires a lot of googling searching.

I really enjoyed the journey I would say. I loved the course and it was really detailed and easy to understand.

just finished this course a few minutes ago and I can't believe that it came to an end so prematurely, it did not go over public cryptography systems and their core principles. also did not dive into symmetric cryptography algorithms and their mechanics, I wish I knew why.

thank you.
