Open p12 files on ios device - ios

Question

I have this requirement to download .p12 file(certificate) from a vendor and make it available on my app for the user to install it on to his device.
Now If I attach a .p12 file to email and when the recipient clicks on the file on iphone it will start installing I am just trying to get the same behavior.
As of now in my app I am able to download the p12 file and store it in the apps documents directory.
func saveCert(serialId : String){
let source = "https://myhost.com/serialId"
let url = NSURL(string: source)
let request = NSURLRequest(URL: url!)
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config)
let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
if (error == nil) {
let statusCode = (response as! NSHTTPURLResponse).statusCode
print("Success: \(statusCode)")
let filename = self.getDocumentsDirectory().stringByAppendingPathComponent("test.p12")
print(filename)
data?.writeToFile(filename, atomically: true)
let filemgr = NSFileManager.defaultManager()
if filemgr.fileExistsAtPath(filename) {
print("File exists")
} else {
print("File not found")
}
}
else {
print("Faulure: %#", error!.localizedDescription);
}
});
task.resume()
}
Now i need to open this file so user will be taken to install profile screens. Please help.

Here is what you want to look at.
and here is an example of how to use it
import Security
let fileManager = NSFileManager.defaultManager()
var resourcePath:String = fileManager.currentDirectoryPath
resourcePath = resourcePath.stringByAppendingString("/dummy.p12")
if fileManager.fileExistsAtPath(resourcePath){
let p12Data: NSData = NSData(contentsOfFile: resourcePath)!
let key : NSString = kSecImportExportPassphrase as NSString
let options : NSDictionary = [key : "password_for_certificate"]
//create variable for holding security information
var privateKeyRef: SecKeyRef? = nil
var items : CFArray?
let securityError: OSStatus = SecPKCS12Import(p12Data, options, &items)
}
Hope that gets you most of the way there.
Edit:
After doing more research, I found this lib that will help you do everything you are looking to do.
