C++ serialize array of uint8

Webuint8_t is an Unsigned 8-bit Integer, and so the range of values it can represent are 0 to 255.. When you typecast your long/large values to uint8_t, you basically only show the least-significant 8-bits.. However, the decryptBlock() and encryptBlock() functions expect an array of bytes, not a single byte..
