CoTURN: How to use TURN REST API?

Question

I have build coturn and run it successfully. ip:192.168.1.111. Now the question I faced is to get the Turn credential through REST API. http://tools.ietf.org/html/draft-ube

Answer 1

Here is my c# implementation with TTL

public string[] GenerateTurnPassword(string username)
{
    long ttl = 3600 * 6;
    var time = DateTimeOffset.Now.ToUnixTimeSeconds() + ttl;
    var newuser = time + ":" + username;
    byte[] key = Encoding.UTF8.GetBytes("YOURSECRET");
    HMACSHA1 hmacsha1 = new HMACSHA1(key);
    byte[] buffer = Encoding.UTF8.GetBytes(newuser);
    MemoryStream stream = new MemoryStream(buffer);
    var hashValue = hmacsha1.ComputeHash(stream);
    string[] arr = new string[2];
    arr[0] = Convert.ToBase64String(hashValue);
    arr[1] = newuser;
    return arr;
}
