core.certmanager: Include ffdhe2048 from RFC 7919 as default DH param This removes one manual (yet undocumented) step that was supposed to be done to get a complete 'intermediate' configuration. This file can be found on the Internet by searching for "ffdhe2048" and can be verified by comparing the hexadecimal representation of p from the RFC with the output of `openssl asn1parse`. Given the preference and prevalence of ECDHE, it seems likely that few would have noticed this.

-- Compatibility layer for bitwise operations

-- First try the bit32 lib
-- Lua 5.3 has it with compat enabled
-- Lua 5.2 has it by default
if _G.bit32 then
	return _G.bit32;
end

do
	-- Lua 5.3 and 5.4 would be able to use native infix operators
	local ok, bitop = pcall(require, "prosody.util.bit53")
	if ok then
		return bitop;
	end
end

error "No bit module found. See https://prosody.im/doc/depends#bitop";
