If you have installed the 8.0 R2022-09 Studio monthly update or a later one provided by Talend, Talend Studio supports the basic authentication for its update repositories, which is implemented using the Eclipse secure storage.

For more information about the update repositories, see Setting up update repositories for Talend Studio and Continuous Integration. For more information about the Eclipse secure storage, see Secure storage.

If the basic authentication is enabled for the update repositories, after the update repositories are configured in Talend Studio, an Authentication dialog box pops up when you open the feature manager or when you relaunch Talend Studio, which allows you to enter your username and password for the update repositories. For more information about configuring update repositories, see Configuring update repositories.

If the update repository for Talend Studio feature packages and the update repository for Talend Studio updates are hosted on different servers, an Authentication dialog box pops up for each of them.

The Eclipse secure storage uses a master password to encrypt and decrypt data. By default:

  • Your username and password for the update repositories get encrypted and decrypted using the default PBEWithMD5AndDES encryption algorithm and an auto-generated master password.
  • The encrypted username and password are persisted in the Eclipse default keyring file ~/.eclipse/org.eclipse.equinox.security/secure_storage.

However, the auto-generated master password and the Eclipse default keyring file are not portable. If you need to share the master password and the keyring file with other Talend Studio instances or if you need to verify the basic authentication for the update repositories in Talend CommandLine or Continuous Integration, you must follow the procedure below to customize the master password and the keyring file. Besides, you can also customize the encryption algorithm to benefit from a higher strength one.

Procedure

  1. To customize the encryption algorithm:
    1. Launch Talend Studio.
    2. From the menu bar, click Window > Preferences to open the Preferences dialog box.
    3. Expand General > Security and click Secure Storage to open the corresponding view.
    4. On the Advanced tab, select an encryption algorithm you want to use from the drop-down list.
    5. Click Apply and Close to save the changes and close the dialog box.
  2. To customize the master password and the keyring file:
    1. Create a new file, for example mymasterpassword, for storing the master password, and add your master password to the file.
      The master password can be any string you want.
    2. Add the following lines at the beginning of the Talend Studio .ini file corresponding to your operating system, where <keyring-file-path> is the absolute path to the keyring file and <master-password-file-path> is the absolute path to the master password file.
      -eclipse.keyring
      <keyring-file-path>
      -eclipse.password
      <master-password-file-path>
    3. Restart Talend Studio to make your changes take effect.
      After verification of the basic authentication for the update repositories, your username and password are persisted in the custom keyring file, and you can then use the custom master password file and the custom keyring file in Talend CommandLine, Continuous Integration, or other Talend Studio instances.
