I can create a wrapper function to read the public/secret keys to hide it from appearing as clear text.

Clearly, as you add more stuff to do, performances will be lower. I strongly recommend you to analyze if column encryption is really what you need for your purposes, because in my little experience it is often too much work with regard to other approaches (e.g., disk and backup encryption).
