Alice and Bob agree to use the prime p = 1373 and the base g = 2 for communications using the Elgamal public key cryptosystem. Alice decides to choose a new private key a = 299 with associated public key A ≡ 2299 ≡ 34 (mod 1373). Bob encrypts a message using Alice’s public key and sends her the ciphertext (c1, c2) = (661, 1325). Decrypt the message.
