Problem(s)
Part 1
1. Write 2 functions - encRSA_agreement() and decRSA_agreement(), each taking 3 inputs and performing encryption and decryption, respectively, as per the following instructions:
- There must be a 2-level encryption
- Three inputs should be: {data, receiver’s public key, sender’s private key} for encryption and {ciphertext, receiver’s private key, sender’s public key}
- Initially, the message should be encrypted using a normal RSA algorithm (receiver’s public key)
- Ciphertext should be again encrypted using the sender’s private key
- Perform similar (2-level) operations for decryption
2. Create two scripts (keyServer_RSA.py and keyClient_RSA.py) using Python socket programming to generate the RSA key pair as per the following method:
- The client should send two prime numbers (p, q) along with the request
- The server should generate an RSA key pair and send it to the client as a response.
- The generator/primitive root should be automatically chosen on the server’s side.
