Compare the time spent on each of the above operations, and describe your observations. If an operation is too fast, you may want to repeat it for many times, i. e., 5000 times, and then take an average rsa aes

Here's the complete question below that clarifies what you need to do

Explanation:

"In this task, we will study the performance of public-key algorithms. Please prepare a file ( message.txt) that contains a 16-byte message. Please also generate an 1024-bit RSA public/private key pair. Then, do the following:

1)Encrypt message.txt using the public key; save the the output in message_enc.txt.

2)Decrypt message_enc.txt using the private key.

3)Encrypt message.txt using a 128-bit AES key.

Compare the time spent on each of the above operations, and describe your observations. If an operation is too fast, you may want to repeat it for many times, i.e., 5000 times, and then take an average.

After you finish the above exercise, you can now use OpenSSL's speed command to do such a benchmarking. Please describe whether your observations are similar to those from the outputs of the speed command?
