Below are three binary ciphertexts resulting from encrypting three ASCII-encoded plaintexts with a stream cipher, all with the same stream cipher key. Your goal is to decrypt the first character of the last ciphertext (C3). 1) Demonstrate your steps to derive the decrypted character. 2) Explain why we have to use a one-time pad for encryption.Ciphertext1: 11011111…Ciphertext2: 10100111…Ciphertext3: 10001111…ASCII Table 000000010010001101000101011001110000NULDLESP0@P·p0001SOHDC1!1AQaq0010STXDC2″2BRbr0011ETXDC3#3CScs0100EOTDC4$4DTdt0101ENQNAK%5EUeu0110ACKSYN&6FVfv0111BELETB’7GWgw1000BSCAN(8HXhx1001HTEM)9IYiy1010LFSUB*:JZjz1011VTESC+;K[k{1100FFFS, N^n~1111SIUS/?O_oDEL
