Swift iOSクライアント証明書認証

利用したいWebサービスにはクライアント証明書が必要です。どうすれば証明書を送信できますか？

さらに詳しく説明すると、SecIdentityRefの作成方法がわかりません。

私のNSURLConnectiondidReceiveAuthenticationChallengeでは、ServerTrustの後に次の条件があります。

else if challenge?.protectionSpace.authenticationMethod == NSURLAuthenticationMethodClientCertificate
    {
        var secIdent : SecIdentityRef = ?????????
        var certCred = NSURLCredential(identity: secIdent, certificates: [getClientCertificate()], persistence: NSURLCredentialPersistence.Permanent)
        challenge?.sender.useCredential(certCred, forAuthenticationChallenge: challenge!)
    }

getClientCertificateメソッド：

func getClientCertificate() -> SecCertificateRef
{
    let mainBundle : NSBundle = NSBundle.mainBundle()
    var mainBund = mainBundle.pathForResource("iosClientCert", ofType: "cer") //exported the cert in der format.
    var key : NSData = NSData(contentsOfFile: mainBund!)!
    var turnToCert : SecCertificateRef = SecCertificateCreateWithData(kCFAllocatorDefault, key).takeRetainedValue()

    return turnToCert;
}

技術的には、私が知っている誰かがSwiftでの実装を必要としたとき、彼はNSURLCredentialオブジェクトを接続に取得するために次のObjective-C実装を使用しました。 PKCS12キーストアに含まれる秘密鍵とX509証明書のペアに基づく 。

申し訳ありませんが、Swiftソリューションではソースにアクセスできません。NSURLCredentialがSwiftに返され、そこでhttpurl接続で直接使用されていることだけがわかっています。これは次のようになります。しかし、これは。

私はiOS開発者ではないので、「Swiftへのブリッジング」の部分であなたを助けることはできません。

    NSURL *URL = [NSURL URLWithString:url];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

編集：ハーハー、非常に面白い、バウンティが上がっている間にあなた自身が気にしないときに私を2回反対票を投じました。 *不平を言う*

とにかく、上記を使用するには、Swiftからアクセスする必要があります。

func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {
    if let p12Data = UserManager.currentP12,
       let credential = CertificateManager.getCredentialsForP12(p12Data) as? NSURLCredential {
            challenge.sender.useCredential(credential, forAuthenticationChallenge: challenge)
    } else {
        UIApplication.sharedApplication().networkActivityIndicatorVisible = false
    }   
}

それはこれを使用します。

+ (id)getCredentialsForP12:(NSData *)p12 {
    NSData* p12data = p12;
    const void *keys[] = {kSecImportExportPassphrase};
    const void *values[] = {CFSTR("thePassword")};
    CFDictionaryRef optionsDictionary = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
    CFArrayRef p12Items;
    OSStatus result = SecPKCS12Import((__bridge CFDataRef) p12data, optionsDictionary, &p12Items);
    if (result == noErr) {
        CFDictionaryRef identityDict = CFArrayGetValueAtIndex(p12Items, 0);
        SecIdentityRef identityApp = (SecIdentityRef) CFDictionaryGetValue(identityDict, kSecImportItemIdentity);
        SecCertificateRef certRef;
        SecIdentityCopyCertificate(identityApp, &certRef);
        SecCertificateRef certArray[1] = {certRef};
        CFArrayRef myCerts = CFArrayCreate(NULL, (void *) certArray, 1, NULL);
        CFRelease(certRef);

        NSURLCredential *credential = [NSURLCredential credentialWithIdentity:identityApp certificates:nil persistence:NSURLCredentialPersistenceNone];
        CFRelease(myCerts);
        return credential;

    }
    else {
        // Certificate is invalid or password is invalid given the certificate
        NSLog(@"Invalid certificate or password");

        UIAlertView* av = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Invalid cert or pass" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles: nil];
        [av show];
        NSError *error = [NSError errorWithDomain:NSOSStatusErrorDomain code:result userInfo:nil];
        return nil;
    }

編集：上記のSwiftバージョンはここにありますが、それはかなり厄介だったので、私たちはそれを使用しませんでした。

            let index: CFIndex = 1
            let password: CFString = "password"
            let key = kSecImportExportPassphrase.takeRetainedValue() as String
            var values = [unsafeAddressOf(password)]
            var keys = [unsafeAddressOf(key)]

            var keyCallbacks = kCFTypeDictionaryKeyCallBacks
            var valueCallbacks = kCFTypeDictionaryValueCallBacks

            if result == noErr {

                let idIndex: CFIndex = 0
                var items = p12items?.takeRetainedValue()

                var identityApp: SecIdentityRef = CFDictionaryGetValue(identityDict, keyAddress) 
                var certRef : Unmanaged<SecCertificateRef>?
                SecIdentityCopyCertificate(identityApp, &certRef)

認証チャレンジに応答するには、クライアント証明書からIDを抽出する必要があります。

struct IdentityAndTrust {

    var identityRef:SecIdentityRef
    var trust:SecTrustRef
    var certArray:NSArray
}

func extractIdentity(certData:NSData, certPassword:String) -> IdentityAndTrust {

    var identityAndTrust:IdentityAndTrust!
    var securityError:OSStatus = errSecSuccess

    var items:Unmanaged<CFArray>?
    let certOptions:CFDictionary = [ kSecImportExportPassphrase.takeRetainedValue() as String: certPassword ];

    // import certificate to read its entries
    securityError = SecPKCS12Import(certData, certOptions, &items);

    if securityError == errSecSuccess {

        let certItems:CFArray = items?.takeUnretainedValue() as CFArray!;
        let certItemsArray:Array = certItems as Array
        let dict:AnyObject? = certItemsArray.first;

        if let certEntry:Dictionary = dict as? Dictionary<String, AnyObject> {

            // grab the identity
            let identityPointer:AnyObject? = certEntry["identity"];
            let secIdentityRef:SecIdentityRef = identityPointer as! SecIdentityRef!;

            // grab the trust
            let trustPointer:AnyObject? = certEntry["trust"];
            let trustRef:SecTrustRef = trustPointer as! SecTrustRef;

            // grab the certificate chain
            var certRef:Unmanaged<SecCertificate>?
            SecIdentityCopyCertificate(secIdentityRef, &certRef);
            let certArray:NSMutableArray = NSMutableArray();
            certArray.addObject(certRef?.takeRetainedValue() as SecCertificateRef!);

            identityAndTrust = IdentityAndTrust(identityRef: secIdentityRef, trust: trustRef, certArray: certArray);
        }
    }

    return identityAndTrust;
}

NSURLSessionDelegateで、次のように認証チャレンジに応答します。

public func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {

    let bundle:NSBundle = NSBundle(forClass: self.dynamicType);
    let bundleCertPath:NSString = bundle.pathForResource("clientCertificateName", ofType: "p12")!;
    let certData:NSData = NSData(contentsOfFile: bundleCertPath as String)!;
    let identityAndTrust:IdentityAndTrust = self.certificateHelper.extractIdentity(certData, certPassword: "C00lp@assword");

    if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodClientCertificate {

        let urlCredential:NSURLCredential = NSURLCredential(
                identity: identityAndTrust.identityRef,
                certificates: identityAndTrust.certArray as [AnyObject],
                persistence: NSURLCredentialPersistence.ForSession);

        completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential, urlCredential);


    } else {

        // nothing here but us chickens
    }
}

私は最後のxcodeとSwiftバージョンを使用しています。このコードは、Bins Ichの回答に基づいて、クライアント証明書.pfxを使用して機能します。

 func extractIdentity(certData:NSData) -> IdentityAndTrust { 
    var identityAndTrust:IdentityAndTrust!
    var securityError:OSStatus = errSecSuccess
    var items:Unmanaged<CFArray>?
    let certOptions:CFDictionary = [ kSecImportExportPassphrase.takeRetainedValue() as String: "password" ];

    // import certificate to read its entries
    securityError = SecPKCS12Import(certData, certOptions, &items);

    if securityError == errSecSuccess {
        let certItems:CFArray = items?.takeUnretainedValue() as CFArray!;
        let certItemsArray:Array = certItems as Array
        let dict:AnyObject? = certItemsArray.first;
        if let certEntry:Dictionary = dict as? Dictionary<String, AnyObject> {

            // grab the identity
            let identityPointer:AnyObject? = certEntry["identity"];
            let secIdentityRef:SecIdentityRef = identityPointer as! SecIdentityRef!;

            // grab the trust
            let trustPointer:AnyObject? = certEntry["trust"];
            let trustRef:SecTrustRef = trustPointer as! SecTrustRef;

            // grab the cert
            let chainPointer:AnyObject? = certEntry["chain"];
            let chainRef:SecCertificateRef = chainPointer as! SecCertificateRef;
            let  certArray:CFArrayRef = chainRef as! CFArrayRef

            identityAndTrust = IdentityAndTrust(identityRef: secIdentityRef, trust: trustRef, certArray:  certArray);
        }
    }
    return identityAndTrust;
}

func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {

    let strTemp = challenge.protectionSpace.authenticationMethod

    if(strTemp == NSURLAuthenticationMethodServerTrust) {
         challenge.sender.continueWithoutCredentialForAuthenticationChallenge(challenge)
    }

    if(strTemp == NSURLAuthenticationMethodClientCertificate) {

        let certFile = NSBundle.mainBundle().pathForResource("mycert", ofType:"pfx")

        let p12Data = NSData(contentsOfFile:certFile!)
        let identityAndTrust:IdentityAndTrust = extractIdentity(p12Data!)

            identity: identityAndTrust.identityRef,
            certificates:identityAndTrust.certArray as [AnyObject],
            persistence: NSURLCredentialPersistence.Permanent)

        challenge.sender.useCredential(urlCredential ,forAuthenticationChallenge:challenge)
    }
