I have to prepare Message Integrity Attribute for TURN allocation request.

say my username is user_1, realm is 192.168.1.101 and password is user_pass_1

key = MD5(user_1:192.168.1.101:user_pass_1)

then I have to perform HMAC-SHA1 on a buffer using above key.

I want to use gnutls library for calculating HMAC-SHA1, is there any way to do it

Try Googling "hmac_sha1.c" – samgak May 10 '16 at 06:41
You can use OpenSSL's `HMAC_xxx` functions to do this – Pierre May 10 '16 at 07:37
