AES Help Please

[jtv]

BTW, I see you're on windows; I only develop for Posix systems, and def don't 
test on wsl2, but OpenSSL should be there on windows. All you need from it are 
aes.nim and random.nim which are built only on OpenSSL, so you should be able 
to yank those two files out.
    I also used `strDump()` and `hex()` from my hex dump module; that module 
does assume Posix as it uses an ioctl to format hex dumps to your terminal 
width. So just use `toHex()` for that.
