Where is $1, $2 etc coming from? Those are special variables that contain contents of regex captures, which you aren't generating here.

You also don't have a variable named $encrypted_data. Is this the code you're using? If not, please edit your post and include it.

Also, add use warnings; and use strict; right above your other use line.
