I am trying to statically add a new security provider to Android. In particular, I want to add additional signature implementations to be used by other applications, not only mine.
Under standard Java there is a file $JAVA_HOME$/lib/security/java.security where I can add a new provider which is then used by all other applications which use the JCA. "Forking" applications to only add one line of code is seems to be a bit of overkill.
However, I cannot find this file under Android. Currently, I am using a Nexus 10 tablet with Android 4.4 for development. Apparently, there the aforementioned file does exist in the Android source, but I was not able to find it on my device. I am not willing/allowed to root/flash the device. I assume that I cannot do this programmatically, but is there another way of adding that provider for all programs? Or where can I find that file?
