Signature for twitter app

I need a signature for my first request to twitter :

 

My code create a Post request to this end Url https://api.twitter.com/oauth/request_token and I have to set a header which is mention below in which I

 

need signature.

 

I have only call back Url, consumer_key. I have created nonce and timestamp. I need signature

 

Authorization Header:
OAuth oauth_nonce="XXXXXXXXX", oauth_callback="XXXX", oauth_signature_method="HMAC-SHA1", oauth_timestamp="XXXXXX", oauth_consumer_key="XXXXXX", oauth_signature="HOW I CREATE THIS", oauth_version="1.0"

urgent for me.
