comment Hill Cipher known plaintext attack
As far as I understand from both of your answers and comments, I should try to recover decryption matrix first, and the encryption key will be just its inverse. I'll try to solve the problem with the information you provided when I get an answer I'll let you know again.

@bob we know that "erkays" is encrypted to "devuao" and the ciphertext to be decrypted is "LQDUIRXSFFHO" and we know its first letter is S. That's all the information.

comment Hill Cipher known plaintext attack
I have another ciphertext that I'm required to decrypt of length 12 and as a hint I know its first letter. The hint should be useful I believe but I could not use it.
