I'm idly wondering to myself if there's an easy way to AES encrypt data, keeping the data locked in memory at all times. (cuz the data is a gpg secret key..)

And then the same day, someone posts a haskell library that elegantly implements that. http://cse.iitk.ac.in/users/ppk/posts/2016-08-02-Handling-Secure-Memory-in-Raaz.html
