The S3 encryption, <u>Server-Side Encryption with Customer-Provided Keys (SSE-C)</u>, allows the company to leverage Amazon S3 for storing data with given constraints.
What do you mean by S3 encryption?
S3 encryption <u>encrypts your </u><u>data </u><u>when it is written to disks in its </u><u>data </u><u>centers at the </u><u>object </u><u>level and decrypts it for you when you </u><u>access </u><u>it.</u> There is no distinction between accessing encrypted or unencrypted items as long as you authenticate your request and you have access permissions.
S3 encryption<u> </u><u>encrypts an item before saving it to disk when you use server-side </u><u>encryption</u><u>; the </u><u>object </u><u>is then decrypted when you download the object</u>. S3 encryption lets you safeguard the data you store in AWS S3 buckets online, which is crucial for sensitive data.

If you encrypt the secret key with someone else's public key, then only that person can decrypt it with his private key. The encrypted content can be freely shared with anyone, however only the intended recipient can retrieve the secret key since he is the only one with the proper private key.
Answer:
The program written in C++ is as follows'
#include<iostream>
using namespace std;
int main()
{
string names[3];
cout<<"Please enter three names: "<<endl;
for (int i = 0; i< 3;i++)
{
cin>>names[i];
}
for (int i = 2; i>= 0;i--)
{
cout<<names[i]<<endl;
}
return 0;
}
Explanation:
This line declares an array for 3 elements
string names[3];
This line prompts user for three names
cout<<"Please enter three names: "<<endl;
This following iteration lets user input the three names
for (int i = 0; i< 3;i++) { cin>>names[i]; }
The following iteration prints the three names in reverse order
for (int i = 2; i>= 0;i--) { cout<<names[i]<<endl; }
