My Android (4.4) device has a WiFi configured which uses WPA2-TLS authentication with client certificates.

I got my hands on the wpa_supplicant configuration and the relevant entry looks like this:

network={
        ssid="fobar"
        key_mgmt=WPA-EAP IEEE8021X
        eap=TLS
        identity="000123"
        password="000000"
        ca_cert="keystore://CACERT_fobar_WPA_EAPIEEE8021X_TLS_NULL"
        client_cert="keystore://USRCERT_fobar_WPA_EAPIEEE8021X_TLS_N"
        engine_id="keystore"
        key_id="USRPKEY_fobar_WPA_EAPIEEE8021X_TLS_NULL"
        engine=1
        proactive_key_caching=1
}

How can I get hold of the certificates and the key?

Go to :

/data/misc/keystore/user_0

And find the file's with similar name like below :

USRCERT_fobar_WPA_EAPIEEE8021X_TLS_N

  • i think these files automatically stored in this directory.and also, this information can help you : ca_cert="keystore://CACERT_fobar_WPA_EAPIEEE8021X_TLS_NULL" client_cert="keystore://USRCERT_fobar_WPA_EAPIEEE8021X_TLS_N" for find and save. Mar 26 '15 at 15:41
