Notation of cryptography

1). Plain text in proper

2). Language

3). Communication media

4). Keys

5). Computer files

6). Security code

Key 

A key is a part of variable data fix into a cryptography algorithm to perform such operation. It can be classified based on their 

a). Systematic key

It is a single key perform encryption I'm a systematic way with help of secret code.

2). Encryption key

It is a also known as public and private key. It is used to describe digital signature and message text value transmitted

Encryption 

It is a process translation of different data in secret code. It is more effective method for data security.

Decryption

It is a process to take encoded data. It is convert into data computer language and able to read and understand.
