Question: There is a method for letter-based stream cipher called Minuend where the value of the plaintext is subtracted from the key using modulo 26 arithmetic.

There is a method for letter-based stream cipher called Minuend where the value of the plaintext is subtracted from the key using modulo 26 arithmetic. The usual encoding of letters is followed, i.e., A->0 and Z->25. If we use the key "SECRET" to encrypt the plaintext "ATTACK" the ciphertext is ( Answer )
