    A nibble is 4 bits. A hexidecimal digit is 4 bits. You can single out a hexidecimal digit by using the binary AND operator. Here's an example:
    Code:
      0xDEADBEEF
    & 0x000F0000
    ----------------
      0x000D0000
    From the number 0xDEADBEEF, the 16^4 hexadecimal digit was singled out.

    if that is the case, then would the files after being incrypted using this method increase in size?
