To get started, the first thing we need to do is create a private key keystore. This is going to be a file on your filesystem, and I'm going to name mine privateKey.store.

Generate Key File From Keystore Windows 10

The following tutorial guides you through the steps to generate a keystore file required to build an Android app for submission to the Google Play Store. We will be using the software KeyStore Explorer to generate the keystore file and Headjack to build the Cardboard VR Play Store App. The screenshots in this tutorial were made in Windows, so the steps might look different when following this tutorial on Mac OS X.

  1. First we need to download and install KeyStore Explorer. Visit the following website http://keystore-explorer.org/index.html and follow the Download button.
  2. Download KeyStore Explorer for your operating system (Windows or Mac OS X recommended). Follow the installation instructions to install KeyStore Explorer. KeyStore Explorer requires Java to be installed on your system. Follow the download and installation instructions on the java website: https://www.java.com/en/
  3. Open KeyStore Explorer and press the button Create a new KeyStore to start creating a keystore file.

  4. Select JKS as the new KeyStore type.
  5. Press the Generate Key Pair button to start filling the keystore file with authentication keys.
  6. In Algorithm Selection keep RSA selected with a Key Size of 2048.
  7. In the next window, make sure Version 3 is selected for Version andSHA-256 with RSA is selected for Signature Algorithm.
    Change the Validity Period to 25 Years.
    The Serial Number field should be left unchanged.
    Now click the book button (Edit name).
  8. Fill in the fields in the next window with your company details. All fields are required!
    Click OK to save these details.
  9. The Name field should now show your company details (abbreviated).
    Press OK to save the key details.
  10. You are now asked to fill in an Alias. Fill in anything, but be sure to note it down, as Headjack will ask you for this Alias later.
  11. Now fill in a Key Password. Keystore files have two (separate) passwords, the Key Password and the (Key)Store Password, make sure to note this password down as your Key Password.
  12. In the list of keystore entries, you should now see your generated key, identifiable by its Alias.
    Press the Save button to store your newly generated key to a keystore file.
  13. Now fill in a Store Password. This password can be different from the Key Password you just filled in, but it does not have to be. Keystore files have two (separate) passwords, the Key Password (which we created in step 11) and the Store Password, make sure to note this password down as your Store Password.
  14. Save the keystore file anywhere, making sure to end the File name with .keystore. Headjack currently only allows you to upload keystore files if they have the .keystore extension.
    !! Make sure you save the keystore file and passwords in a safe place, because you need them for future updates of your app. If you lose them you can never update your app again in the Play Store.
  15. The keystore file has now been successfully generated, and you can close KeyStore Explorer.
    To use this keystore to build a Play Store app on Headjack, head to the App Signing page under Settings in Headjack, or follow this link: https://app.headjack.io/#/settings/signing
  16. Now press Add signing files to upload your keystore file to Headjack, or follow this link: https://app.headjack.io/#/settings/signing/add
  17. Under Select platform… select either Cardboard Android or Daydream depending on the desired app.
    Select the Store checkbox and fill in the previously entered Alias in the appropriate field.
    Now press Upload Keystore to upload your keystore file.
  18. Select the .keystore file you just saved and press Open to upload it.
  19. The filename of your .keystore file should now display next to the Upload Keystore button and a green bar will fill to the right indicating your file is being uploaded.
    When the bar has filled up, press Save to save these App signing credentials.
  20. To build a Play Store app in Headjack, navigate to the app’s page and you will find the Build menu to the right.
    Under Select platform, select the same platform as the signing credentials selection (Cardboard Android or Daydream).
    Select the Store checkbox and the Select signing credentials button should appear. Click that button.
  21. In the Select signing credentials list, press Choose on the keystore credentials you just uploaded to Headjack. The name of those credentials should display under the Select signing credentials button.
  22. Now fill in the Store password and Key password with the two passwords previously entered when creating the keystore file, making sure not to mix up the two passwords.

Now it is just a case of pressing Build Application and Headjack will notify you by email when the app has finished building and is ready to be uploaded to the Play Store!

Generating a KeyStore and TrustStore

The following sections explain how to create both a KeyStoreand a TrustStore (or import a certificate into an existing TrustStoresuch as the default Logical Host TrustStore in the location:


where <c:JavaCAPS> isthe directory where Java CAPS is installed and <MyDomain> isthe name of your domain. The primary tool used is keytool, but openssl isalso used as a reference for generating pkcs12 KeyStores.

For more information on openssl andavailable downloads, visit the following web site:

Creating a KeyStore in JKS Format

This section explains how to create a KeyStore using theJKS format as the database format for both the private key, and theassociated certificate or certificate chain. By default, as specifiedin the java.security file, keytool usesJKS as the format of the key and certificate databases (KeyStore andTrustStores). A CA must sign the certificate signing request (CSR).The CA is therefore trusted by the server-side application to whichthe Adapter is connected.

Note –

Itis recommended to use the default KeyStore

To Generate a KeyStore

  1. Perform the following command.


  2. Once prompted, enter the information required to generatea CSR. A sample key generation section follows.


    If the KeyStore password is specified, then the password mustbe provided for the adapter.

  3. Press RETURN when prompted for the key password (thisaction makes the key password the same as the KeyStore password).

    This operation creates a KeyStore file clientkeystore in the current working directory. You must specify a fullyqualified domain for the “first and last name” question.The reason for this use is that some CAs such as VeriSign expect thisproperties to be a fully qualified domain name.

    Thereare CAs that do not require the fully qualified domain, but it isrecommended to use the fully qualified domain name for the sake ofportability. All the other information given must be valid. If theinformation cannot be validated, a CA such as VeriSign does not signa generated CSR for this entry.

    This KeyStore containsan entry with an alias of client.This entry consists of the generated private key and information neededfor generating a CSR as follows:


    This command generates a certificate signing request which canbe provided to a CA for a certificate request. The file client.csr contains the CSR in PEM format.

    Some CA (one trusted by the web server to which the adapteris connecting) must sign the CSR. The CA generates a certificate forthe corresponding CSR and signs the certificate with its private key.For more information, visit the following web sites:

    or

    If the certificate is chained with the CA’scertificate, perform step 4; otherwise, perform step 5 in the followinglist:

  4. Perform the following command.


    The command imports the certificate and assumes the client certificateis in the file client.cer and theCA’s certificate is in the file CARoot.cer.

  5. Perform the following command to import the CA’scertificate into the KeyStore for chaining with the client’scertificate.


  6. Perform the following command to import the client’scertificate signed by the CA whose certificate was imported in thepreceding step.


    The generated file clientkeystore containsthe client’s private key and the associated certificate chainused for client authentication and signing. The KeyStore and/or clientkeystore, can then be used as the adapter’sKeyStore.

Creating a KeyStore in PKCS12 Format

This section explains how to create a PKCS12 KeyStoreto work with JSSE. In a real working environment, a customer couldalready have an existing private key and certificate (signed by aknown CA). In this case, JKS format cannot be used, because it doesnot allow the user to import/export the private key through keytool. It is necessary to generate a PKCS12database consisting of the private key and its certificate.

The generated PKCS12 database can then be used as the Adapter’sKeyStore. The keytool utility iscurrently lacking the ability to write to a PKCS12 database. However,it can read from a PKCS12 database.

Note –

There are additional third-party tools available for generatingPKCS12 certificates, if you want to use a different tool.

For the following example, openssl isused to generate the PKCS12 KeyStore:


From

The existing key is in the file mykey.pem.txt in PEM format. The certificate is in mycertificate.pem.txt, which is also in PEM format. A textfile must be created which contains the key followed by the certificateas follows:


This command prompts the user for a password. The password isrequired. The KeyStore fails to work with JSSE without a password.This password must also be supplied as the password for the Adapter’sKeyStore password.

This command also uses the openssl pkcs12 commandto generate a PKCS12 KeyStore with the private key and certificate.The generated KeyStore is mykeystore.pkcs12 withan entry specified by the myAlias alias.This entry contains the private key and the certificate provided bythe -in argument. The noiter and nomaciter optionsmust be specified to allow the generated KeyStore to be recognizedproperly by JSSE.

Creating a TrustStore

For demonstration purposes, suppose you have the followingCAs that you trust: firstCA.cert, secondCA.cert,thirdCA.cert, located in the directory C:cascerts. You can create a new TrustStore consistingof these three trusted certificates.

To Create a New TrustStore

How To Open Key File Icon

  1. Perform the following command.


  2. Enter this command two more times, but for the secondand third entries, substitute secondCA and thirdCA for firstCA.Each of these command entries has the following purposes:

    • The first entry creates a KeyStore file named myTrustStore in the current working directoryand imports the firstCA certificateinto the TrustStore with an alias of firstCA.The format of myTrustStore is JKS.

    • For the second entry, substitute secondCA to import the secondCA certificateinto the TrustStore, myTrustStore.

    • For the third entry, substitute thirdCA to import the thirdCA certificateinto the TrustStore.

    Once completed, myTrustStore is available to be used as theTrustStore for the adapter.
