Abstract The Session Traversal Utilities for NAT (STUN) protocol defines two STUN attributes -- FINGERPRINT and MESSAGE-INTEGRITY -- that may be included in STUN messages. This document provides test vectors for those two attributes. Denis-Courmont Expires September 11, 2008 [Page 1] Internet-Draft STUN test vectors March 2008 Table of Contents 1.

Introduction The Session Traversal Utilities for NAT (STUN)[I-D.ietf-behave-rfc3489bis] protocol defines two different 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 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 ICE Connectivity Checks use case of STUN, (see [I-D.ietf-mmusic-ice]). These messages include FINGERPRINT, MESSAGE- INTEGRITY and XOR-MAPPED-ADDRESS STUN attributes. These attributes are considered to be most prone to implementation errors. In the following sample messages, two types of plain UTF-8 text attributes are included. The value of these attributes were purposedly sized to require padding. In this document, ASCII white spaces (U+0020) are used for padding - this is arbitrary. As per [I-D.ietf-behave-rfc3489bis], padding bytes can have any value. 2.1.
