What is Cryptography means technically ?

[KaliLinux]

Hi All,

Just want to know about cryptography. I have bit knowledge that its created by mathematical style. Did any one is studying about this like as a course?

Cryptography have much future in upcoming years ?

i thinks it's like making a structural design of something , from its name cryptography that has the word graph which means write down or making a diagram . in my idea i think it is a developing of a cryptocurrency and also it uses a programming language because it is under the programming i think . and yes it uses and created with mathematical calculation of a computer . maybe if you are a programmer you are able to learn all about this crytography .

I have no idea why you're asking a general question such as this when there is so much information available online? You just simply need to use a search engine. Wikipedia says the following:

Cryptography or cryptology is the practice and study of techniques for secure communication in the presence of third parties called adversaries. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, and electrical engineering.

Here you can find everything that you need.

That's cryptography, you are already using it every day. So it's not the future, it's the present (and the recent past, too).

(and the recent past, too).

Cryptography, in some aspects, has been used since antiquity, although the methods were far less refined (basic substitution, Vigenere, and so on) as compared to today. In this day and age, it's fairly useful to get a good amount of number theory and discrete mathematics in order before setting off in in-depth analysis of how cryptographic algorithms are created and what makes them secure. It's also helpful to know the mathematical nuts and bolts when creating cryptosystems, but simple prudence and the correct use of known-secure algorithms as recommended and documented is a very good initial start.
