SAMLResponse

[sorrin_scouse]

Hello guys! I tried to decipher this SAML Response, it worked, it shows the string on the screen. Now I want to to do the opposite, to deflate the response, from string to binary, do I have to change something in the code or use another function?

The entire code is here:

<!--- We take a base64 encoded, deflated SAML response string --->

<cfset SAMLResponse = "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" />

<!--- We convert the string to binary and a ByteArrayInputStream to be able to read the stream --->

<cfset byteIn = createObject("java", "java.io.ByteArrayInputStream").init(ToBinary(SAMLResponse)) />

<cfset byteClass = CreateObject("Java", "java.lang.Byte").TYPE />

<cfset byteArray = CreateObject("Java", "java.lang.reflect.Array").NewInstance(byteClass, 1024) />

<!--- We init the output object where we are going to inflate our response --->

<cfset byteOut = CreateObject("Java", "java.io.ByteArrayOutputStream").init() />

<!--- We init the zip inflater --->

<cfset inflater = CreateObject("Java", "java.util.zip.Inflater").init(true) />

<!--- We are specifying to the ibnflater what to read --->

<cfset inflaterStream = CreateObject("Java", "java.util.zip.InflaterInputStream").init(byteIn, inflater) />

<!--- We loop through our byte array, inflate the buffer and store it inside of our output buffer --->

<cfset Count = inflaterStream.read(byteArray) />

<cfloop condition="Count neq -1">

<cfset byteOut.write(byteArray, 0, Count) />

<cfset Count = inflaterStream.read(byteArray) />

</cfloop>

<!--- We end/close our inflater --->

<cfset inflater.end() />

<cfset inflaterStream.close() />

<!--- Finally we convert back our bytes stream to a nice string🙂 --->

<cfset inflatedSAMLResponse = ToString(byteOut.tobyteArray()) />

<cfdump var="#inflatedSAMLResponse#" />
