我想要使用的Web服务需要客户端证书。我如何将证书发送给它？
为了进一步阐述，我不明白如何创建SecIdentityRef。
在我的NSURLConnection didReceiveAuthenticationChallenge我ServerTrust后有条件：
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方法：
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;
}

从技术上讲，当我认识的人需要在Swift中实现时，他使用以下Objective-C实现来获取连接的NSURLCredential对象; based on the private key and X509 Certificate pair contained in a PKCS12 keystore
抱歉，我无法使用Swift解决方案访问源代码。我所知道的是NSURLCredential被返回到Swift，并直接在那里的http url连接中使用。但它与此类似。
我不是iOS开发人员，所以我无法帮助你解决“桥接到Swift”的问题。

无论如何，要使用上面的内容，您只需要从Swift访问它。
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
}
}
使用它。

为了响应身份验证质询，您需要从客户端证书中提取身份。
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;
}
在NSURLSessionDelegate中响应身份验证质询：
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
}
}

我正在使用最后的xcode和swift版本，这个代码对我来说很有用，使用客户端证书.pfx，基于Bins Ich回答：
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!)
let urlCredential:NSURLCredential = NSURLCredential(
identity: identityAndTrust.identityRef,
certificates:identityAndTrust.certArray as [AnyObject],
persistence: NSURLCredentialPersistence.Permanent)
challenge.sender.useCredential(urlCredential ,forAuthenticationChallenge:challenge)
}
}
