$8\mathrm{.}13.$ Encrypt the following messages with the Elgamal scheme $($p $=467$ and $\backslash$alpha $=2)$ :

$1.$ kpr $=$ d $=105,$ i $=213,$ x $=33$

$2.$ kpr $=$ d $=105,$ i $=123,$ x $=33$

$3.$ kpr $=$ d $=300,$ i $=45,$ x $=248$

$4.$ kpr $=$ d $=300,$ i $=47,$ x $=248$

Now decrypt every ciphertext and show all steps.
