Create a Java KeyStore certificate

Encrypt the security certificates obtained from Google by creating a Java KeyStore (JKS) file.

Before you begin

• Role required: admin

• Download a JSON file containing the service account key from Google. For information on downloading the JSON file, see the Google documentation. Following is a sample JSON file:

  {
    "type": "service_account",
    "project_id": "primeval-nectar-242610",
    "private_key_id": "0c6c7b1511f1c236c1300c5933d528bbf45314e5",
    "private_key": "-----BEGIN PRIVATE KEY-----\n...\n-----END PRIVATE KEY-----\n",
    "client_email": "service-now-google-trans-v3@primeval-nectar-242610.iam.gserviceaccount.com",
    "client_id": "113255944370425109391",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/service-now-google-trans-v3%40primeval-nectar-242610.iam.gserviceaccount.com"
  }
  

Procedure

1. In the JSON file, perform the following for the private_key value.

   1. Unescape the \n characters.

      Tip: To unescape characters in a JSON file, you can parse a JSON string into a JavaScript object.

   2. Store the private key in a file with .pem extension.

2. In the JSON file, perform the following for the client_x509_cert_url value.

   1. Open the link specified for client_x509_cert_url.

   2. Unescape the \n characters for the certificate associated with the private_key_id mentioned in the JSON file.

   3. Store the certificate value in a file with .pem extension.

3. Use the openssl command to create a PKCS 12 file using the recently created private key and certificate files.

   openssl pkcs12 -export -in [path to certificate] -inkey [path to private key] -certfile [path to certificate ] -out testkeystore.p12
   

   For example, if certificate.pem is the certficate and privatekey.pem is the private key:

   openssl pkcs12 -export -in certificate.pem -inkey privatekey.pem -certfile certificate.pem -out testkeystore.p12
   

   A PKCS 12 file, testkeystore.p12, is created.

4. Specify an export password or source keystore password.

   Note: You should specify this password when creating a JWT key for Google Cloud Translator Service spoke.

5. Use the keytool command to create a JKS file from the PKCS 12 file.

   keytool -importkeystore -srckeystore testkeystore.p12 -srcstoretype pkcs12 -destkeystore wso2carbon.jks -deststoretype JKS
   

   Note: testKeyStore.p12 is the PKCS 12 file and wso2carbon.jks is the JKS file.

6. Specify a destination keystore password.

   Note: You should specify this password when attaching a JKS certificate to Google Cloud Translator Service spoke.
