Hi guys Approved by CloudFlare, I'm now opensourcing the experimental ssl_certificate_by_lua and ssl_certificate_by_lua_file directives in the ngx_lua modul...

random string in resty

yahel.bahat

Hi

How can i transform resty.random bytes into a randomized string ?
the string can contain all (or a subset) of alpha numeric chars.

Hello,

lua-resty-string contains a to_hex() method. You can use it like so

str.to_hex(random)

Thank you.

I'm aware of that function.
I would like to know if there is a function that can output [0-9A-Za-z] chars ?

Here is such a function that you may copy and paste

https://github.com/bungle/lua-resty-random/blob/master/lib/resty/random.lua#L58-L75

I need to rename that random library to something else, as there is a name conflict with lua-resty-string, but you can copy and paste the code.

Thanks,

Why the token function is using number (math.random) and not the bytes (C.RAND_pseudo_bytes) ?

LuaJIT uses a Tausworthe PRNG with period 2^223 to implement math.random. It's easy though to use random.bytes and make a number out of it (it is also easy to get it wrong).
