<p class="MsoNormal">I’m trying to programmatically encode and decode AuthnRequest XML. Which technologies are used and what steps would I follow to do this? If I understand correctly, the typical process goes like this:</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">To encode:</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">1. Convert XML to byte stream</p>
</div>
<div>
<p class="MsoNormal">2. Compress the byte stream</p>
</div>
<div>
<p class="MsoNormal">3. Base64 encode the compressed stream</p>
</div>
<div>
<p class="MsoNormal">4. UrlEncode the Base64 string </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">To decode:</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">1. UrlDecode the string</p>

<div>
<p class="MsoNormal">2. Base64 Decode the UrlDecoded string</p>

<p class="MsoNormal"> </p>

<div>
<p class="MsoNormal">When I try to decode the AuthnRequest that we are passing to an IDP, I don’t get anything usable. I’ve tried GZip and .Net’s DeflateStream. Do I have the encoding and decoding process corrent? What compression does shib use? Is the
XML signed with a cert?</p>
