Layout ActivationInfo

This is the plist file which gets sent to Apple's server

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
 <dict>
       <key>ActivationInfoComplete</key>
       <true/>
       <key>ActivationInfoXML</key>
       
       (base64-encoded activation info here)
       
       <key>FairPlayCertChain</key>
       
       (base64-encoded cert in DER format)
       
       <key>FairPlaySignature</key>
       
       (base64-encoded signature (SHA1+RSA) of ActivationInfoXML)

Key: ActivationInfoXML

The ActivationInfo plist file above has a key called ActivationInfoXML. The base64 data value of that key represents the plist file below

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Spoofing the Activation Server using python

Here's a python script to spoof it:

import httplib,urllib
import time
ai=open("a.plist",'r')
aidata=ai.read()
conn = httplib.HTTPSConnection("albert.apple.com")
headers = {"Content-type": "application/x-www-form-urlencoded", "User-Agent": 'iTunes/7.6 (Windows; U; Microsoft Windows XP Professional Service Pack 2 (Build 2600)) DPI/96}'}
params = urllib.urlencode({
	'activation-info': aidata
	})
conn.request('POST', '/WebObjects/ALActivation.woa/wa/deviceActivation',params,headers)
response = conn.getresponse()
resdata=response.read()
f=open("arsp.xml",'w')
f.write(resdata)
#time.sleep(1)
