Some test data that can be used when parsing stun messages (WebRTC/ICE/STUN)

Parsing_Stun.txt

Below is a dump of a STUN message that can be used to validate your 
STUN message integrity check. The password that is used to encrypt
the Message-Integrity is: "Q9wQj99nsQzldVI5ZuGXbEWRK5RhRXdC" (without quotes)

In C/C++ notation:
-------------------
const unsigned char respv4[] = "\x00\x01\x00\x58\x21\x12\xa4\x42\x48\x75\x38\x77\x4e\x4f\x49\x53\x62\x54\x65\x4a\x00\x06\x00\x1b\x35\x50\x4e\x32\x71\x6d\x57\x71\x42\x6c\x3a\x34\x68\x52\x42\x6d\x66\x4b\x48\x75\x58\x6a\x4f\x67\x6b\x56\x4a\x00\x80\x2a\x00\x08\xd2\xdb\x70\x25\x70\x6b\xcd\x98\x00\x25\x00\x00\x00\x24\x00\x04\x6e\x7f\x1e\xff\x00\x08\x00\x14\x5a\xca\x22\xd7\xf4\x39\xfa\xde\xaf\xd3\x9b\xd6\xec\x00\xd4\x96\xe2\x17\x09\x32\x80\x28\x00\x04\x78\x5d\x2e\xeb";

My parser produces the following output:
-----------------------------------------
Msg: STUN_BINDING_REQUEST, Type: STUN_ATTR_USERNAME,            Length: 27,     bytes left: 84, current index: 24

The HMAC-SHA1 is computed over (note that we changes the Message-Length in the Stun header):
