How do you add a .p12 certificate to an Android device?

Question

I\'m having trouble loading a .p12 certificate to my Android project. Here is a chunk of source code:

char[] password = "".toCharArra         


        

Answer 1

Try this

File cert = new File("mnt/sdcard/" + filename + ".p12");
InputStream inputStreamFromDownload = null;

keyStore = KeyStore.getInstance("PKCS12");
inputStreamFromDownload = new BufferedInputStream(new FileInputStream(cert));

Log.i("Certificate", inputStreamFromDownload.available() + "");

Answer 2

...

In Android, I see people programmatically install keystore in the following way (The code is from Android developer blog):

byte[] keystore = . . (read from a PKCS#12 keystore)

Intent installIntent = KeyChain.createInstallIntent();
installIntent.putExtra(KeyChain.EXTRA_PKCS12, keystore);
startActivityForResult(installIntent, INSTALL_KEYSTORE_CODE);

I also see people programmatically install only the certificate wrapped inside keystore:

Intent intent = KeyChain.createInstallIntent();
intent.putExtra(KeyChain.EXTRA_CERTIFICATE, cert);
startActivity(intent);
