The SSLPost Document Encryption Plugin can be installed via the Plugin Manager. As the Administrator of your Confluence instance
After the plugin is installed you should be able to see the following screen, please note the "SSLPost" tab on the left under Configuration
After successfully installing the SSLPost plugin, you must create a "manager" account for each domain that your users are part of, for example anyone who has an email address associated to a domain must have a manager account associated. The manager account should not be a natural person and could be setup as either an inbox or a distribution box on your Corporate Mail server. An example would be "email@example.com"
To signup for a manager account please create an SSLPost account at https://secure.sslpost.com/app/signup , once you have signed up you will receive a validation email where by you can set your account password, it is suggested you select a sufficiently complex password, a minimum of 8 characters , 1 uppercase and 1 lowercase is mandatory.
After you have completed the signup process for the manager user, please email firstname.lastname@example.org to request the account is configured with the manager and send on behalf of flag. If you already have a user who exists in the domain, you will need the user to be associated with the manager, if the user is new to SSLPost the association will be automatic once they send a document or page from within Confluence
The Configuration of the SSLPost plugin requires Administrator level access to your Confluence Instance
The default URI configuration is https://secure.sslpost.com/app/xml/encrypt/ , if you are using a Whitelabel version of SSLPost you will need to modify the URI to point at your instance.
An email domain which includes the domain , manager user and password is required for each domain that may exist within your confluence instance. For instance if users are using sslpost.com and example.com within your confluence instance for their email addresses, you will need a manager user for each of these. Manager users are linked to a domain and users are associated automatically if the user sends an email or document from within Confluence.
