Problem 1: Implement ElGamal system Your code will accept prime p and a generator a. Then a user will pick either key generation (k), message signature (s) or message verification (v) option. Key generation: program will randomly pick a secret X₂ and output private and public key. Message signature: user will provide m. Program will use random k. You should use EEA to computer k-¹. Output (S₁, S2). Instead of using H(m), just use m. So for us H(m)-m identity function. This will make computations slower as value of m can be large. Message verification: user provides all required information and program will decide if the signature is valid.
