Cryptography what is it?

I can't understand about cryptography. What is it mean? I search on internet abount cryptography but I can't understand.

I can't understand about cryptography. What is it mean? I search on internet abount cryptography but I can't understand.

How did you try to understand it? Have you tried viewing videos or something similar?
I personally learn everything through the internet and I can say most of the times there are a lot of resources that can give you great insight about the topics that you wanted to learn.

Which site that you use to learn about cryptography? What kind of understanding that you want to achieve? Just to know what is cryptography or learn how to do it?

If it's only about definition, Wikipedia should be able to help you: https://en.wikipedia.org/wiki/Cryptography.

Here's advice from me. If for some reason you don't clearly understand a Wikipedia definition of something, do this.

Here's the page:
https://en.wikipedia.org/wiki/Cryptography

Change it to:
https://simple.wikipedia.org/wiki/Cryptography

The Wikipedia definition now should me significantly easy to understand for non-technical people.

In an understandable form possible, Cryptography is a process of protecting sensitive data, making it unreadable to an unauthorized party which has to do with encoding (i.e encrypting that sensitive data) making use of hash algorithms e.g SHA- 256 (which is used by bitcoin) and decoding (i.e decrypting by the recieving party) for it to be accessible (readable).

Cryptography serves as the data and security of cryptocurrency and the blockchain, KT serve as the record house and the compass to all crypto transactions and it security with records, I think this is the little I understand about cryptography.

Say you want to transfer data from a to b, without a third party c being able to read it, or edit this data without b knowing. You need to encrypt the data with a key that only a & b has access to, so that even if intercepted this data is unreadable & useless without a key. If intercepted it can be tampered with or replaced, so b also needs a way to check if the data has been tampered with – this is where methods such as hash functions & digital signatures can be used.
