    description
      "This module describes a YANG model for keychain configuration
and management. These keys can be changed frequently to
increase security in long-lived connections. A keychain can be used
for authenticaion in a number of scenarios, including in routing protocols
(e.g. BGP, IS-IS, OSPF).  A keychain provides a solution for storing
a number of different keys, each key string value is associated with a
specific key id, name, the lifetime that the key is valid and an
encryption algorithm.

This model defines a central location for defining named keychains,
which may be then referenced by other models such as routing protocol
management.";
