Base64 Encoding AND Decoding in Corona SDK

Base64 Encoding

function base64.encode(data)
 local len = data:len()
 local t = {}
 for i=1,len,384 do
  local n = math.min(384, len+1-i)
  if n > 0 then
   local s = data:sub(i, i+n-1)
   local enc, _ = mime.b64(s)
   t[#t+1] = enc
  end
 end

 return table.concat(t)
end

Base64 Decoding


function base64.decode(data)
 local len = data:len()
 local t = {}
 for i=1,len,384 do
  local n = math.min(384, len+1-i)
  if n > 0 then
   local s = data:sub(i, i+n-1)
   local dec, _ = mime.unb64(s)
   t[#t+1] = dec
  end
 end
 return table.concat(t)
end

If you get mime error just add this
local mime = require("mime")
