iOS – SSL握手 – 客户端证书 – NSURLSession – NSURLErrorDomain代码= -1200 – 错误的链

我正在尝试使用带有Objective C的iPhone调用web服务,我遇到以下错误:

error –>Error Domain=NSURLErrorDomain Code=-1200 “An SSL error has
occurred and a secure connection to the server cannot be made.”
UserInfo={_kCFStreamErrorCodeKey=-9806,
NSLocalizedRecoverySuggestion=Would you like to connect to the server
anyway?, NSUnderlyingError=0x600000243690 {Error
Domain=kCFErrorDomainCFNetwork Code=-1200 “(null)”
UserInfo={_kCFStreamPropertySSLClientCertificateState=0,
_kCFNetworkCFStreamSSLErrorOriginalValue=-9806, _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9806}}, NSLocalizedDescription=An SSL error has occurred and a secure
connection to the server cannot be made.,
NSErrorFailingURLKey=https://./,
NSErrorFailingURLStringKey=https://
./,
_kCFStreamErrorDomainKey=3}

Info.plist配置

<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

有关服务器的信息:

TLS 1.2
客户端证书身份验证要求ON
密码列表:

> TLS_RSA_WITH_AES_256_CBC_SHA256
> TLS_RSA_WITH_AES_128_CBC_SHA256
> TLS_RSA_WITH_AES_256_CBC_SHA
> TLS_RSA_WITH_AES_128_CBC_SHA
> TLS_RSA_WITH_3DES_EDE_CBC_SHA

注意:在客户端(iOS)和服务器中间添加管理客户端证书的charles代理后,请求成功完成.因此,我可以得出结论,我使用的客户端证书是有效的.

任何建议我如何解决这个问题或任何线索我做错了哪个配置?

我的猜测是关于客户端证书配置,因为我已经使用完全相同的配置与类似的服务(ssl层/服务器密码),不需要客户端证书身份验证.

编辑额外信息

在一些wirehark调查之后,似乎iOS正在发送客户端证书两次,服务器关闭连接.

尝试了这里指定的解决方案:http://oso.com.pl/?p=207&lang=en但它打破了我的所有代码

最佳答案 解决方案现在

在比较成功请求(android)和iOS失败请求之间的wireshark数据包之后,我注意到iOS单独发送客户端证书,而Android和Charles Proxy正在发送客户端证书完整链.

我还在调查哪个是在iOS上没有发送完整链的原因.也许是因为它不信任签署客户端证书的中间证书和根证书?

无论如何,我设法通过使用以下代码锤击发送的链来使SSL握手在iOS上工作:

  NSString *sslCertName = @"teste_webservices";
  NSString *path2 = [[NSBundle mainBundle] pathForResource:sslCertName ofType:@"p12"];
  NSData *p12data = [NSData dataWithContentsOfFile:path2];

  CFDataRef inP12data = (__bridge CFDataRef) p12data;

  SecIdentityRef myIdentity;
  SecTrustRef myTrust;

  extractIdentityAndTrust(inP12data, &myIdentity, &myTrust);


  NSData *ca1CertData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"ca1" ofType:@"cer"]];
  SecCertificateRef ca1CertRef = SecCertificateCreateWithData(kCFAllocatorDefault, (CFDataRef) ca1CertData);
  NSData *rootCertData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"rootCa" ofType:@"cer"]];
  SecCertificateRef rootCertRef = SecCertificateCreateWithData(kCFAllocatorDefault, (CFDataRef) rootCertData);


  SecCertificateRef myCertificate;
  SecIdentityCopyCertificate(myIdentity, &myCertificate);
  const void *certs[] = {ca1CertRef, rootCertRef};

  CFArrayRef certsArray = CFArrayCreate(NULL, certs, 2, NULL);

  CFRelease(myCertificate);

  secureCredential = [NSURLCredential credentialWithIdentity:myIdentity
                                                certificates:(__bridge NSArray *) certsArray
                                                 persistence:NSURLCredentialPersistencePermanent];
