Creation Some array creation functions allow you to specify the data type. douglas wilkisonWebuint8_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. douglas wilkinson obituary

This has the side effects of having a defined behavior on underflow (subtracting one to 0) and overflow (adding 1 to 255). It also is always 8 bits even on platforms where a byte is not 8 bits. It means that contrary to int, you get identical operation on all platforms.
