This is because, here we are going to help you out.
If you want to convert the information available with you into a code which is not accessible at everyone’s disposal, then this is called encryption.
If you want to encrypt data in such a way that no one else gets the key to decrypt it.
Then you need to use asymmetric encryption.
In this type of encryption, you need to have separate keys for both encryption and decryption.
The key which is used for the decryption of code is available on the server.
On the other hand, if the developer has a lot of data, then it might take a lot of time.
This is because of the reason that you need to work very long on the making of these keys.
Encryption through different approaches :
First of all, you have to generate a random key of a reasonable length for your code.
Then, you will encrypt your data with the help of symmetric approach.
This means that you are going to use the same key for both encryption and decryption purposes.
You can use the public key for this purpose.
In this method, all you need to do is to store the asymmetric encrypted key as well as the symmetric data.
The next task will be done on the server.
Here you have to decrypt the key with the help of a private key.
Whatever the results you get will be used in order to decrypt the data.
Here, we would like to add that it is not necessary that encryption of data will authenticate the customer.
It is very simple to understand that anyone can get the data which is present on the server.
So, the key must not be available publically.
