iPhone:HTTPS 客户端证书认证 [英] iPhone: HTTPS client cert authentication
问题描述
我正在与客户端证书身份验证作斗争.当服务器需要一个凭证(在这种情况下是一个证书)时，这个方法会从 NSURLConnection 委托中调用:
I'm fighting with a client certificate authentication. When a server needs a credential (a certificate in this case), this method is invoked from NSURLConnection delegate:
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
我想从文件中加载证书，填写凭据并运行此方法:
I want to load a certificate from a file, fill a credential and run this method:
[[challenge sender] useCredential:[self credential] forAuthenticationChallenge:challenge];
但我不知道如何初始化(或填充)SecIdentityRef 参数.这是我创建凭据的代码:
But I don't know how to initialize (or fill) a SecIdentityRef parameter. Here is my code that creates the credentials:
NSString *certPath = [[NSBundle mainBundle] pathForResource:@"certificate" ofType:@"cer"];
NSData *certData = [[NSData alloc] initWithContentsOfFile:certPath];
SecIdentityRef myIdentity; // ???
SecCertificateRef myCert = SecCertificateCreateWithData(NULL, (CFDataRef)certData);
[certData release];
SecCertificateRef certArray[1] = { myCert };
CFArrayRef myCerts = CFArrayCreate(NULL, (void *)certArray, 1, NULL);
CFRelease(myCert);
NSURLCredential *credential = [NSURLCredential credentialWithIdentity:myIdentity
certificates:(NSArray *)myCerts
persistence:NSURLCredentialPersistencePermanent];
CFRelease(myCerts);
有人知道怎么解决吗?谢谢.
Does anybody know how to solve it? Thanks.
我终于找到了解决办法，但是又出现了一个新问题:
I've finally found the solution, but a new problem is here:
我的客户端没有将证书发送到服务器.服务器请求证书后，应用程序运行此方法:
my client doesn't send the certificate to the server. After the server asks for the certificate, the application runs this method:
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
我填写了凭据(就像我上面提到的那样)，但连接以错误结束:NSURLErrorDomain -1206.根据服务器日志，客户端证书不是由应用程序发送的.
and I fill the credential (like I mentioned above), but the connection ends with an error: NSURLErrorDomain -1206. According to the server logs the client certificate is not sent by the application.
有人遇到过这种行为吗?我是否需要以某种方式验证应用程序中的证书?或者还有什么可以让它工作的?如果有帮助，我可以提供我当前的代码.感谢您的任何想法...
Has anybody any experience with this behaviour? Do I need to somehow verify the certificate in the application? Or anything else to make it work? I can provide my current code if it helps. Thanks for any ideas...
推荐答案
我使用这些步骤:
- 使用 SecPKCS12Import 函数从 pkcs12 证书文件中提取 SecIdentityRef
- 使用 SecIdentityCopyCertificate 函数获取 SecCertificateRef
其余的(凭据初始化)与我的问题相同...如果您愿意，我可以在此处放置更多代码.请注意，iphone 中有一个错误 (http://openradar.appspot.com/7090030)模拟器，因此无法在模拟器中使用大量证书.
and the rest (a credential initialization) is the same as in my question... I can put here more code if you want. Note that there is a bug (http://openradar.appspot.com/7090030) in the iphone simulator, so it is not possible to work with a lot of certifcates in the simulator.
