• A simple client server model which performs a public key and elements transfer and then by using them and it performs the signature verification whenever a new signed messsage is provided with same elements.
• Code is written in Python

Multithreaded server which provides signature verification

$ ./server.sh

Client which provides message input, key generation and Signature generation support.

$ ./server.sh [ IP address of server ]

• client.log - maintains a log session for client operations.
• server.log - maintains a log session for server operations.

Takes care of Public key, public elements generation, signing of the message and also verification.

• modinv - calculates inverse modulo
• extended_gcd - calculates extended gcd for two inputs
• keyGeneration - generates public key elements and key.
• signatureGeneration - generates signature over provided message
• signatureVerification - performs verification over message signature with provided old values.

all forms of packet creation is done via this module

• createPubKeyMsg - Packet for public key elements
• createSignedMsg - Packet for message and signature details
• createVerstatus - Packet for response of signature verification.
• packMessage - Trivial serialization
• unpackMessage - Trivial unserialization

provides extremely basic logging capabilities

• minilogger.writer - append or fresh log file operations

module to perform all prime number calculcations

• is_prime - test if prime or not
• generate_prime_number - returns a prime number
• generate_prime_candidate - limits the bound for prime number
• prim_root - calculates primitive root of the prime number provided
