Any question
For simplicity, let's use the example of a mailbox
Jia Ning has a secret message to tell Pierre
She puts the message into the mailbox and locks it with a key
Pierre comes over, opens the box with a key, and reads Jia Ning's message
The process of locking the message in the box is called encryption, and the process of unlocking the box is called decryption
When we talk about encrypting messages on a computer or device, the key used to "unlock" the message is called a password
A password is a code that can scramble or decode text
There are various encryption methods, but WinRAR uses AES 256-bit encryption technology. This standard is adopted by military forces, governments, and financial institutions worldwide
