[SIPForum-discussion] How digest response is generated

[Stephen James]

The MD5 sum for the digest includes other elements than just the password. Read RFC 2617 for the components that go into the MD5 sum calculations.

Subject: [SIPForum-discussion] How digest response is generated
 


 
Hi,

I am testing my sip dialer using 
HTTP digest authentication in the server side. Now, my dialer is sending the below response:

Digest username="bob", realm="192.168.146.133", nonce="5e954418", uri="sip:192.168.146.133", response="ec221690633f2ae691669c4083832fd8", algorithm=MD5

However, the original password that I set was 1234 and the md5 value of 1234 is 81dc9bdb52d04dc20036dbd8313ed055 (according to http://www.miraclesalad.com/webtools/md5.php) Now how do I match the password? can someone provide me the exact algorithm of generating this digest response so that I can write a function? 

Someone please help.
