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.

RFC 5769 STUN Test Vectors April 2010
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
