Integrating VouchSafe with phpBB

Getting Started

To get started with VouchSafe, you need to do the following:

  1. Create an account and register your domain with us to get a public / private key pair for your website.
  2. Download the VouchSafe package for phpBB from the VouchSafe downloads page.

The guide below will give you step-by-step instructions for installing and configuring VouchSafe on your PhpBB discussion board.


Step-by-Step Instructions

  1. First you need to merge the folders from the package with your phpBB installation. Unzip the archive, and copy the folders inside the “root” folder in the package.  Paste them into the root folder of your phpBB installation.  If prompted to do so, select the option to merge the folders.  This will include the VouchSafe module content with the rest of your phpBB install.

  3. Log into the phpBB admin console, select the “System” tab, and press the “Add Module” button to add a new module.

  15. You’ll be presented with the management pop-up for a new keyset.  Here you can type in your top-level domain name, and configure the way VouchSafe will be presented on your website. In general, you should not select the “Global” option, (this is for use where you want to be able to publish VouchSafe validated content on other websites).

    You can select the button style, the interface style, and the background color for the VouchSafe pop-up. When you’re done, press the “Create KeySet” button to generate a key pair for your domain.

  17. You should now see the new key pair for your domain, (shown highlighted in the image below). These are the values you need to copy into the module configuration panel on your PhpBB website. You can always change the settings for your site later on by logging back into your account and pressing the “Edit” button for your keyset.  If you wish, you can manage multiple domains from the same VouchSafe account by simply creating new keysets.
