Converting inputStream to FileInputStream?

Question

I am in a problem - i need to read SecretKey from Android APK (e.g. key.keystore), for my app it has to be read as a FileInputStream, but from assets I am getting only input

Answer 1

Why do you need a FileInputStream specifically? In general, you don't have to care about the underlying implementation of the InputStream, you just read from it. Maybe your implementation should be InputStream agnostic.
