	do

	if [[ -f $filename ]]; then

	function password_from_keychain(service)
	-- 'service' should be saved in the login keychain
	local cmd = "/usr/bin/security 2>&1 >/dev/null find-generic-password -gs '" .. service .. "' \| sed -En '/^password: / s,^password: \"(.*)\"$,\\1,p'"

	local handle = io.popen(cmd)
	local result = handle:read("*a")
	handle:close()

	return (result:gsub("^%s(.-)%s$", "%1"))
	end
