For educational reasons I've decided to create my own CA. Here is what I learned.
Lets get some context first.
local random = math.random | |
local function uuid() | |
local template ='xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx' | |
return string.gsub(template, '[xy]', function (c) | |
local v = (c == 'x') and random(0, 0xf) or random(8, 0xb) | |
return string.format('%x', v) | |
end) | |
end |
