How to process a HttpResponse blob zip file

In my application, i am sending an HttpRequest to an external server to get a zip file, and once it's done i get the response as Blob, but i don't know how to process the Blob to extract some files from it.
This is the code: 
HttpRequest request = new HttpRequest();

 /* Here i set the Endpoint, body, and method attributes*/

Http http = new Http();                
HttpResponse response = http.send(request);

 Blob file = response.getBodyAsBlob();

/*Here i should process the Blob (which is a zip file) to extract my files*/
Help please.. !!

I finally found an answer to deal with this problem, i posted it in Stackoverflow. Here's the link: http://stackoverflow.com/questions/31993430/salesforce-extract-files-within-blob-zip-file

It's a work-arround: I create a StaticResource with the Metadata API of salesforce, but before i had to add a new Remote Site with the current instance of Salesforce.  to be able to call the method of the API.
Then i create a PageReference Object with the content of the file name within the StaticResource zip file.

This can be done with the Zippex library. It's open source and available here https://github.com/pdalcol/Zippex
  
HttpRequest request = new HttpRequest();

//Set the Endpoint, body, and method attributes

Http http = new Http();                
HttpResponse response = http.send(request);

Blob file = response.getBodyAsBlob();

//Instantiate Zippex with zip file Blob
Zippex zip = Zippex(file);

for (String fileName : zip.getFileNames()) {	
    //Extract file
    Blob fileData = zip.getFile(fileName);
    //Process the file here
    ...
}
