斯威夫特的iOS客户端证书认证 [英] Swift iOS Client Certificate Authentication
本文介绍了斯威夫特的iOS客户端证书认证的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
该网站的服务，我想消费，需要一个客户端证书。我怎样才能把我的证书呢？
要进一步阐述我不明白如何创建 SecIdentityRef 。
在我的 NSURLConnection的 didReceiveAuthenticationChallenge 我在 ServerTrust ：
如果挑战别的吗？.protectionSpace.authenticationMethod == NSURLAuthenticationMethodClientCertificate
{
VAR secIdent：SecIdentityRef = ?????????
VAR certCred = NSURLCredential（身份：secIdent，证书：[getClientCertificate（）]，持久性：NSURLCredentialPersistence.Permanent）
挑战.sender.useCredential？（certCred，forAuthenticationChallenge：挑战！）
}
的 getClientCertificate 方法：
FUNC getClientCertificate（） - GT; SecCertificateRef
{
让mainBundle：一个NSBundle = NSBundle.mainBundle（）
VAR mainBund = mainBundle.pathForResource（iosClientCert，ofType：CER）//导出的证书DER格式。
VAR键：NSData的NSData的=（contentsOfFile：mainBund）！
VAR turnToCert：SecCertificateRef = SecCertificateCreateWithData（kCFAllocatorDefault，键）.takeRetainedValue（） 返回turnToCert;
}
解决方案
从技术上讲，如果有人知道我需要实施斯威夫特，他使用，以获得NSURLCredential对象的连接下面的Objective-C的实施;基于包含在一个PKCS12密钥库私钥和X509证书对。
对不起，我没有获得与斯威夫特的解决方案的来源。我所知道的是，NSURLCredential返回到斯威夫特，并直接在HTTP URL连接有使用。这是与此类似，虽然。
我不是一个iOS的开发，所以我不能帮你解决了桥接雨燕的一部分。

不管怎么说，使用上面下面，你只需要从斯威夫特访问它。
FUNC连接（连接：NSURLConnection的，willSendRequestForAuthenticationChallenge挑战：NSURLAuthenticationChallenge）{
如果让p12Data = UserManager.currentP12，
让凭证= CertificateManager.getCredentialsForP12（p12Data）作为？ NSURLCredential {
challenge.sender.useCredential（凭证，forAuthenticationChallenge：挑战）
}其他{
UIApplication.sharedApplication（）。networkActivityIndicatorVisible = FALSE
}
}
使用此。

NSData的* p12data = P12;
常量无效*键[] = {} kSecImportExportPassphrase;
常量无效*值[] = {CFSTR（thePassword）};
CFDictionaryRef optionsDictionary = CFDictionaryCreate（NULL，键，值1，NULL，NULL）;
CFArrayRef p12Items;
OSStatus结果= SecPKCS12Import（（__桥CFDataRef）p12data，optionsDictionary，＆安培; p12Items）;
如果（结果==诺尔）{
CFDictionaryRef identityDict = CFArrayGetValueAtIndex（p12Items，0）;
SecIdentityRef identityApp =（SecIdentityRef）CFDictionaryGetValue（identityDict，kSecImportItemIdentity）;
SecCertificateRef certRef;
SecIdentityCopyCertificate（identityApp，＆安培; certRef）;
SecCertificateRef certArray [1] = {certRef};
CFArrayRef myCerts = CFArrayCreate（NULL，（无效*）certArray，1，NULL）;
CFRelease（certRef）; NSURLCredential *证书= [NSURLCredential credentialWithIdentity：identityApp证书：无持久性：NSURLCredentialPersistenceNone];
CFRelease（myCerts）;
返回凭证; }
其他{

回零;
}
编辑：上面的一个迅速的版本是在这里，虽然这是很混乱的，我们只是宁可不使用它
VAR p12items：非托管＆LT; CFArrayRef＆GT ;? 让指数：CFIndex = 1

让键= kSecImportExportPassphrase.takeRetainedValue（）作为字符串
变种值= [unsafeAddressOf（密码）]
VAR键= [unsafeAddressOf（钥匙） VAR keyCallbacks = kCFTypeDictionaryKeyCallBacks
VAR valueCallbacks = kCFTypeDictionaryValueCallBacks 让长度：CFIndex = p12Data.length
让p12CfData：CFData = CFDataCreate（kCFAllocatorDefault，UnsafePointer＆LT;＆UINT8 GT;（p12Data.bytes），长度） 让选项= CFDictionaryCreate（kCFAllocatorDefault，和放大器;键，＆安培;价值指数，和放大器; keyCallbacks，＆安培; valueCallbacks）
让结果= SecPKCS12Import（p12CfData，期权和放大器; p12items） 如果结果== {诺尔 让idIndex：CFIndex = 0
VAR项目= p12items？.takeRetainedValue（）
VAR identityDict = CFArrayGetValueAtIndex（项目！idIndex） VAR键= kSecImportItemIdentity.takeRetainedValue（）作为字符串
VAR keyAddress = unsafeAddressOf（键）
VAR identityApp：SecIdentityRef = CFDictionaryGetValue（identityDict，keyAddress）
VAR certRef：非托管＆LT; SecCertificateRef＆GT ;?
SecIdentityCopyCertificate（identityApp，＆安培; certRef） VAR证书：SecCertificateRef = certRef .takeRetainedValue（）！
VAR certArray = [unsafeAddressOf（CERT）
VAR arrayCallback = kCFTypeArrayCallBacks
VAR myCerts：CFArrayRef = CFArrayCreate（kCFAllocatorDefault，＆安培; certArray，索引和安培; arrayCallback）; 让凭据：NSURLCredential = NSURLCredential（身份：identityApp，证书：[AnyObject]（），持久性：NSURLCredentialPersistence.None）
The web service I want to consume requires a client certificate. How can I send my certificate to it?
To further elaborate I don't understand how to create the SecIdentityRef.
In my NSURLConnection didReceiveAuthenticationChallenge I've got this conditional after ServerTrust:
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!)
}
The getClientCertificate method:
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;
}
解决方案
Technically, when someone I know needed the implementation in Swift, he used the following Objective-C implementation in order to get the NSURLCredential object to the connection; based on the private key and X509 Certificate pair contained in a PKCS12 keystore.
Sorry, I don't have access to the source with the Swift solution. All I know is that the NSURLCredential was returned to Swift, and used directly in the http url connection there. It's similar to this one, though.
I'm not an iOS dev so I won't be able to help you out with the "bridging to Swift" part.

EDIT: Har har, very funny, downvoting me twice when you yourself didn't bother while the bounty was up. *grumble *
Anyways, to use the following above, you just need to access it from Swift.
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
}
}
That uses this.
+ (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;
}
EDIT: A swift version of the above is here, although it was messy enough that we rather just didn't use it.
var p12items : Unmanaged<CFArrayRef>?
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
let length: CFIndex = p12Data.length
let p12CfData: CFData = CFDataCreate(kCFAllocatorDefault, UnsafePointer<UInt8>(p12Data.bytes), length)
let options = CFDictionaryCreate(kCFAllocatorDefault, &keys, &values, index, &keyCallbacks, &valueCallbacks)
let result = SecPKCS12Import(p12CfData, options, &p12items)
if result == noErr {
let idIndex: CFIndex = 0
var items = p12items?.takeRetainedValue()
var identityDict = CFArrayGetValueAtIndex(items!, idIndex)
var key = kSecImportItemIdentity.takeRetainedValue() as String
var keyAddress = unsafeAddressOf(key)
var identityApp: SecIdentityRef = CFDictionaryGetValue(identityDict, keyAddress)
var certRef : Unmanaged<SecCertificateRef>?
SecIdentityCopyCertificate(identityApp, &certRef)
var cert: SecCertificateRef = certRef!.takeRetainedValue()
var certArray = [unsafeAddressOf(cert)]
var arrayCallback = kCFTypeArrayCallBacks
var myCerts: CFArrayRef = CFArrayCreate(kCFAllocatorDefault, &certArray, index, &arrayCallback);
let credential: NSURLCredential = NSURLCredential(identity: identityApp, certificates: [AnyObject](), persistence: NSURLCredentialPersistence.None)
