A4: Generating Authentication-Info and response #66
Comments
Were you able to resolve your issue after our discussion in the last lecture? |
Hey, I'm still having trouble with this one. I am currently returning something like this for
From that I get a "ASSERTION: Authentication-Info header should contain bd71b2ef47de1e9c3d1e4a0382f41982, returned cnonce="014a54548c61ba03827ef6a4dc2f7b4c", nc="00000001", qop=auth". Not sure what I'm doing wrong here. The only Idea I have is i'm supposed to include something based on my generated nonce...?

Hello,
I'm having some trouble with generating the response and Authentication-info hash in my assignment. According to the slides (assuming we're using md5) response = md5(md5(A1):nonce:ncount:cnonce:qop:md5(A2)) and Authentication-info = md5(:URI) unless I'm misunderstanding this is not producing the expected results in my code. Any help is appreciated, thank you.
