Outline helps users bypass restrictions to access the open internet. Here's are
some key concepts to understand how it works:
Service providers and end users
The Outline system involves two main roles: service providers, who manage
the servers, and end users, who access the internet through those servers.
- Service providers create the Outline servers, generate access keys,
and distribute the keys to end users. One way to do this is using the
Outline Manager application.
- End users install the Outline Client application, paste in the
access key they received, and connect to a secure tunnel.
Access keys
Access keys are the credentials that allow users to connect to an Outline
server. They contain the necessary information for the Outline Client to
establish a secure connection. There are two types of access keys:
Static access keys encode all the server information needed to connect
(server address, port, password, encryption method), preventing the access
information from being modified. Users paste this key into the Outline
Client.
Example:
ss://Y2hhY2hhMjAtaWV0Zi1wb2x5MTMwNTo1UkVmeFRqbHR6Mkw@outline-server.example.com:17178/?outline=1
Dynamic access keys allow a service provider to host the server access
information remotely. This lets providers update their server configuration
(server address, port, passwords, encryption method) without needing to
reissue new access keys to end users. For more detailed documentation, see
Dynamic Access
Keys.

Users experiencing blocked access can utilize Outline Manager to create a server on the cloud and generate unique access keys. These keys are then distributed to other users. Users install the Outline client and input their provided keys. This action establishes a secure tunnel, allowing them to bypass restrictions and access the open internet.\n"]]
