help peleas with that Q$1)$ The following was encrypted with a Playfair Cipher with keyword Galois $1.$ Decrypt the message. AQOOUNGCIEYEOKVNEUNBCCCLOKIH. $2.$ Construct a Playfair Square with keyword cryptology $3.$ Use the square from exercise $2$ to encrypt the message. Welcome to Jordan Note: It uses the most common rules for Playfair cipher: $1.\text{'}$ J $\text{'}$ is replaced with $\text{'}$T$\text{'}$ to fit $5\backslash$times $5$ square $2.\text{'}$ Z $\text{'}$ is used as a substitution in case you need to fill the second letter in the diagram or split two identical letters $3.$ Playfair square is filled row$-$by$-$row, starting with the keyword. Q$2)$ Deerypt the ciphertext "FIMFTO" $,$ using Hill cipher for the given key

$[[23$; $36]]$

Q$3)$ Encrypt the plaintext "safe messages", using Hill cipher for the given key: "ciphering".
