Assume-Zhan / RSA-encryption-decryption

Simple RSA encryption and decryption

Setup time

• Input : n or (p, q)
  • Select n or primes (p, q) to input
  • ⚠️ n must need demux into 2 primes
  • p and q must be two primes
  • Ex :
    • If Q given n : input (n, -1, -1)
    • If Q given p, q : input (-1, p, q)
• Input e :
  • Can setup by itself or given
  • Ex :
    • If Q given e : just input e
    • If Q not given e : input -1

Public and private key

• Public key : [n, e]
• Private key : [n, d]

Enc, Dec

• Mode : "enc"
  • Input : original message
  • Output : encrypted message
• Mode : "dec"
  • Input : encrypted message
  • Output : original message
• Instruction :
  • "chmod" : toggle the mode
  • "exit" : exit

Usage

• Just run simulation.py
