I’m trying to implement some crypto into my Scala source, so in my algorithm, I would need some null byte, so as in Scala it would be like

0x00 as Byte
 (originally as algorithm stated)
u0000 ? (Scala format)

There wasn’t any problem with the null byte, but when I try to convert a decimal, I would got an extra demand on little-endian 64-bit unsigned integer, as demo showcased:

value 45 is showed as x2d (some other lang idk)
Scala: ? 

Is there anyway or any library can help on this one ? I’m not really familiar with Scala enough to solve this one. TYIA 🙂
