      Test Vectors for Session Traversal Utilities for NAT (STUN)

Abstract

   The Session Traversal Utilities for NAT (STUN) protocol defines
   several STUN attributes.  The content of some of these --
   FINGERPRINT, MESSAGE-INTEGRITY, and XOR-MAPPED-ADDRESS -- involve
   binary-logical operations (hashing, xor).  This document provides
   test vectors for those attributes.

1.  Introduction

   The Session Traversal Utilities for NAT (STUN)[RFC5389] protocol
   defines two different hashes that may be included in messages
   exchanged by peers implementing that protocol:

   FINGERPRINT attribute:  a 32-bit Cyclic Redundancy Check.

   MESSAGE-INTEGRITY attribute:  an HMAC-SHA1 [RFC2104] authentication
      code.

   This document provides samples of properly formatted STUN messages
   including these hashes, for the sake of testing implementations of
   the STUN protocol.

2.  Test Vectors

   All included vectors are represented as a series of hexadecimal
   values in network byte order.  Each pair of hexadecimal digits
   represents one byte.

   Messages follow the Interactive Connectivity Establishment (ICE)
   Connectivity Checks use case of STUN (see [RFC5245]).  These messages
   include FINGERPRINT, MESSAGE-INTEGRITY, and XOR-MAPPED-ADDRESS STUN
