2.4. Client configuration
- Clients need to make their authorization data known to Tor using another
- configuration option that contains a service name (mainly for the sake of
- convenience), the service address, and the descriptor cookie that is
- required to access a hidden service (the authorization protocol number is
- encoded in the descriptor cookie):
+ To specify the cookie to use to access a given hidden service,
+ clients use the following syntax:
+
+ HidServAuth onion-address auth-cookie [service-name]:
+
+ Valid onion addresses contain 16 characters in a-z2-7 plus
+ ".onion", and valid auth cookies contain 22 characters in
+ A-Za-z0-9+/. The service name is only used for internal purposes,
+ e.g., for Tor controllers; nothing in Tor itself requires or uses
+ it.
