In this article, you can learn about cryptography and you can easily understand how it works through simple examples in this article.

Crypto is called cryptocurrency, Crypto is a word that comes from cryptography. Now everyone can invest and purchase cryptocurrency in Global cryptocurrency exchange platforms.

But understand the word crypto that comes from and know about cryptography by reading the following content.

Cryptography:

Cryptography means to transfer a text or SMS to someone secretly by using encryption and decryption methods. Crypto is a word that comes from Cryptography. 

The purpose of using encryption and decryption methods is to keep transfer data safe and secure. To avoid hackers stealing data, and sending a text secretly and privately we use cryptography. 

What is Encryption and Decryption?

Encryption means converting an original text into a mixing of letters and numbers to avoid the original text publicizing and transferring secretly. 

For example, User A needs to send an SMS like “I have 50 Parkcoins” to User B. 

But A wants to send this SMS to B secretly without leaking or showing it to Everyone. 

So A Encrypts his text by converting “I have 50 Parkcoins” to “wht4vd8njdy654” by using his Keys.

Now B receives a text from A like “wht4vd8njdy654” then B also has a Key, B uses his key to decrypt a text from A.

Decrypts means converting back an improper text to proper text like mixing of letters and numbers to Original text.

Finally, B receives a mix of letters and numbers words from A, then B decrypts by using his key and gets back an Original SMS that “I have 50 Parkcoins”.

Keys in Encryption and Decryption:

There are two keys: Public keys and Private keys, also called Key pairs. 

Both users A and B have both keys, public and private keys. If User A public key encrypts a text that text can only be decrypted by User A's private key.

Public keys can be seen and used by anyone, but private keys are only for personal use and must be kept secret. 

Now see the scenario: User A encrypts his text by using User B's public key and sends it to B. Now User B receives an encrypted text from A then B can decrypt a Text by using his secret private key.
