$step1="$method\\n $datestring\\n $appid\\n $path";

That looks unusual. Why the double backslashes? Why the whitespace? Were you specifically instructed to create $step1 like this?

Yes, apologies step1 is to be constructed this way.

a sample string is "GET\n Wed, 08 Apr 2015 21:37:33 GMT \n1b700d2e7b7b4abfa1950c865e23e81a\n /xxxxxxx/api/v1/users/jsmith/factors"
