Abstract
This document includes test vectors for the MESSAGE-INTEGRITY and
FINGERPRINT attributes of the STUN protocol.
1. Introduction
The Session Traversal Utilities for NAT
(STUN)[I-D.ietf-behave-rfc3489bis] protocol defines two different

Internet-Draft STUN test vectors August 2007
hashes that may be included in messages exchanged by peers
implementing that protocol:
FINGERPRINT attribute: a 32-bits Circular Redundancy Check.
MESSAGE-INTEGRITY attribute: a HMAC-SHA1 authentication code.
This document documents sample properly-formatted STUN messages
including these hashes, for the sake of testing implementations of
the STUN protocol.
HELP: we need other implementors to double-check these!
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 ICE Connectivity Checks use case of STUN, (see
[I-D.ietf-mmusic-ice]). They include both FINGERPRINT and MESSAGE-
INTEGRITY attributes.
2.1. Sample request
This request uses the following parameters:
Username: "evtj:h6vY" (without quotes)
Password: "VOkJxbRl1RmTxUk/WvJxBt" (without quotes)
