        Title           : Extensible Provisioning Protocol (EPP) Secure Authorization Information for Transfer

   The Extensible Provisioning Protocol (EPP), in RFC 5730, defines the
   use of authorization information to authorize a transfer.  The
   authorization information is object-specific and has been defined in
   the EPP Domain Name Mapping, in RFC 5731, and the EPP Contact
   Mapping, in RFC 5733, as password-based authorization information.
   Other authorization mechanisms can be used, but in practice the
   password-based authorization information has been used at the time of
   object create, managed with the object update, and used to authorize
   an object transfer request.  What has not been fully considered is
   the security of the authorization information that includes the
   complexity of the authorization information, the time-to-live (TTL)
   of the authorization information, and where and how the authorization
   information is stored.  This document defines an operational
   practice, using the EPP RFCs, that leverages the use of strong random
   authorization information values that are short-lived, that are not
   stored by the client, and that are stored using a cryptographic hash
   by the server to provide for secure authorization information used
   for transfers.
