BIND Configuration File Guide - key Statement

Syntax

key key_id {
  algorithm algorithm_id;
  secret secret_string;
};

Definition and Usage

The key statement defines a key ID that you can use in a server statement to associate an authentication method with a particular name server.

You must create a key ID with the key statement before you can use it in a server definition.

The algorithm_id string specifies a security/authentication algorithm. The secret_string string is the secret to be used by the algorithm.

The key statement is intended for future use by the server. It is checked for syntax, but is otherwise ignored.
