    • After you configure the HTTPS certificate through the Edge Encryption proxy installer, configure the AES 128-bit encryption key to encrypt your data.

    Before you begin

    Role required: admin

    About this task

    The encryption key is either a plain text file inside the /keys directory or a secret key inside a keystore. If you use a keystore for your AES 128-bit and AES 256-bit encryption keys, they must both use the same keystore.

    If you are updating an SSL certificate on an Edge proxy server, see Update SSL certificate.

    Procedure

    1. Select the encryption key location.
      OptionDescription
      File Store Use a file to store a single encryption key. You can use an existing file in the /keys directory, or you can generate a new file. To generate a new file, enter an alias and click Generate. A file containing an encryption key is created.
      Note:
      This choice designates both the storage location and the encryption key. If you select File Store, click Next and go to step 5.
      Create New Java KeyStore Create a keystore to store the encryption key.
      Java KeyStore File Store the encryption key in an existing Java KeyStore file.
    2. Click Next.
    3. Select or create the encryption key.
      OptionDescription
      New Key Create an encryption key and alias.
      Note:
      You must use lowercase letters and numbers for the alias name (key name, key alias), per Java KeyStore requirements. To find out more about the keytool utility, see the Java SE Documentation.
      Use Existing Key Use an existing encryption key in the selected keystore.
      Import Existing Key Import an encryption key from a different keystore.
    4. Click Next.
    5. Configure the key on the instance according to the requirements defined in your installer.
      To configure the key on the instance, navigate to the instance and define a default key. See Configure encryption keys on the instance. Ensure that the key alias, size, and type match the requirements defined in the installer.
    6. Once the key is configured on the instance, return to the installer and click Next.
