What is cryptography?
Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries).More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.
Yeah, I know that you have read the above lines many times. These are perfectly true jargons. It’s just something like our brain is made of 80% of water, technically true but it doesn’t explain things much.
When I tried to study Cryptography, it was tough. When anyone wants to learn HTML, he can find a lots of resources on internet but when things come to Cryptography you need to buy a lots of books and watch a lots of youtube videos which contains an annoying background music. A lots of blog are also helpful but all are fragmented. So, I decided that it is a good time to put Cryptography course. The course will be beginners friendly and will teach you a lot of things about Information Security.
This series is not meant for 2 communities of people over the internet.
1. Not bothered about Computer Security
2. True Computer professional [Advanced programmers and crypto masters]
The category one does not fit into any computer security course as information security comes at very last in their priority list. Hence, most of the time they are the practice playgrounds for most of the hackers.
The category two has moved into the immense knowledge of information security. And they know all the stuff or most of the present stuff about it. So, they will feel bore in this series because they are the inventor of most of the stuff. Rest of the people are going to love this cryptography online video series.
The candidates for which I am looking to take this cryptography course are:
1. University Students
a. Fretos : The freshers
b. Practos: The practical ones
University Students will be interested in this course as most of the Universities have curriculum of Cryptography. The second category is of hackers but I have divided them into 2 major categories. First one is Fretos, these are fresher in information security and are trying to learn stuff. It is a good time for them to start this series because you will understand terms like MITM, RSA, MD5 and DSA. Second category is hackers who have learned most of the things practically. Personally, I am very impressed that you have gained so much of knowledge. You might have knowledge about hacking into various accounts and systems or even knowledge of creating exploits. But ask a simple question to yourself, you are a pro in hacking skills but have no idea about RSA or Block ciphers. You know to break WEP in wireless but no idea of WEP encryption or cryptic flaw in algorithm.
I hope that you have got my point. So, let’s get started.
