    • 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:

    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.
