"On the host, the user public/private key pair is automatically generated, if it does not exist, when the adb daemon starts and is stored in $HOME/.android/adb_key(.pub) or in $ANDROID_SDK_HOME on windows. If needed, the ADB_KEYS_PATH env variable may be set to a :-separated (; under Windows) list of private keys, e.g. company-wide or vendor keys. On the device, vendors public keys are installed at build time in /adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys"
