C/C++ code in order to store private keys in Android app -
i'm trying find best way store private keys in android app. proguard not enough , dexguard sounds nice little bit expensive me..
what important thing hiding (or hardening see) api access keys in case. result of few days try , error, found using c code looks useful.
my questions are...
・do think using c/c++ way hide private keys?
・i'm using android studio. maybe can use ndk(native development kit). think ndk easier way others? (i've never used ndk)
thanks,
fyi
it impossible save key safely in client app. java can decompiled easily. proguard makes harder. c++ seems harder, not impossible decompile. have aware of hackers can find key if save in client app.
easiest way, open lib , try search key text. probably, see somewhere in binary file
