In this article, we will know Cryptography in easy language. So let's start……
Cryptography:--
This is a technique. In which plain text is converted into ciphertext. Some keys are used in this process. By which the sender and receiver encrypt and decrypt the message.
Plain Text: --
A simple message is called plain text.

Ciphertext: --
The transformation of plain text into the form of code is called ciphertext.
Encryption: --
The process of converting plain text to ciphertext and the key is called encryption.
Decryption: --
By using a cipher, the process of converting ciphertext into plain text and key is called decryption.
Cipher: --
The algorithm or technology used to convert a plain text to ciphertext. it's called a cipher
Key: --
Only the sender and receiver know some important information used in the ciphertext called a key.
Features of cryptography:-
1. Confidentiality:-
Confidentiality means to secure sensitive information. In this, the main role of cryptography is done. Because no person can access any confidential information without keys.
2. Integrity:-
It has three rounds.
(a) no user may modify or edit any information.
(b) it reserves external and internal consistency.
(c) Modifications can be done only by the authorized user.
3. Identification:-
Through this, the identification of the user is done through the system.
Ex:- User's login id
4. Authentication:-
Through this, the identity of the user is verified.
Ex:- password of the user
5. Availability:-
It is ensured by this. The user can log in to the system at any time without any interruption.
