Import .p12-file into AndroidKeyStore

Question

The user has saved a .p12-file (e.g. his S/MIME certificate) on SD-Card. I want to load this certificate (or the extracted private and public key) into the AndroidKeyStore.

Answer 1

If you want to install your certificate into the android KeyChain you can use your P12 to install it directly like in the next method:

    InputStream is = new ByteArrayInputStream(pkcs12);
    BufferedInputStream bis = new BufferedInputStream(is);
    byte[] keychainP12 = new byte[bis.available()];
    bis.read(keychainP12);
    Intent installIntent = KeyChain.createInstallIntent();
    installIntent.putExtra(KeyChain.EXTRA_PKCS12, keychainP12);
    context.startActivity(installIntent);
