【问题描述】：

我面临 OpenSSL 证书创建和安装相关的问题，或者可能是由于 NSURLConnection，我创建了 OpenSSL 证书 following this。

这是错误的本地化描述

2015-07-24 14:47:32.279 SSLTest[7657:60489] CFNetwork SSLHandshake failed (-9824 -> -9829)
2015-07-24 14:47:32.347 SSLTest[7657:60489] NSURLConnection/CFURLConnection       
HTTP load failed (kCFStreamErrorDomainSSL, -9829)
2015-07-24 14:47:32.576 SSLTest[7657:60350] The server “localhost” requires a client certificate.

每次我收到“服务器 'localhost' 需要客户端证书”错误时。

这是我的 .m

- (void)viewDidLoad
{
   [super viewDidLoad];

   NSString *url = @"https://localhost/Test.php";

   NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
   [theRequest setHTTPMethod:@"POST"];

   NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES];
   [theConnection start];
}

#pragma mark - NSURLConnectionDelegate

- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{    
    if ([[challenge protectionSpace] authenticationMethod] == NSURLAuthenticationMethodServerTrust) {
       [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
    } else if ([[challenge protectionSpace] authenticationMethod] == NSURLAuthenticationMethodClientCertificate) {

       SecIdentityRef identity = [self getClientCertificate];
       SecCertificateRef certificateRef;
       SecIdentityCopyCertificate(identity, &certificateRef);
       CFArrayRef certificateArray = CFArrayCreate(NULL, (const void **)certificateRef, 1, NULL);

       NSURLCredential *identityCredential = [NSURLCredential credentialWithIdentity:identity certificates:(__bridge NSArray *)certificateArray persistence:NSURLCredentialPersistenceForSession];
       [challenge.sender useCredential:identityCredential forAuthenticationChallenge:challenge];
   }
 }

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
   NSLog(@"%@",[error localizedDescription]);
}

#pragma mark - Certificates

- (SecIdentityRef)getClientCertificate {
    SecIdentityRef identityApp = nil;
    NSString *thePath = [[NSBundle mainBundle] pathForResource:@"client" ofType:@"p12"];
    NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:thePath];
    CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
    CFStringRef password = CFSTR("abcXYZ123");
    const void *keys[] = { kSecImportExportPassphrase };
    const void *values[] = { password };
    CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
    CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
    OSStatus securityError = SecPKCS12Import(inPKCS12Data, options, &items);
    CFRelease(options);
    CFRelease(password);
    if (securityError == errSecSuccess) {
         NSLog(@"Success opening p12 certificate. Items: %ld",       CFArrayGetCount(items));
    CFDictionaryRef identityDict = CFArrayGetValueAtIndex(items, 0);
    identityApp = (SecIdentityRef)CFDictionaryGetValue(identityDict, kSecImportItemIdentity);
} else {
    NSLog(@"Error opening Certificate.");
}
return identityApp;
}

我的 httpd.config 看起来像这样（我的本地 mac-mini 系统上有 BITNAMI XAMPP 5.6.8）

Alias /bitnami/ "/Applications/XAMPP/xamppfiles/apache2/htdocs/"
Alias /bitnami "/Applications/XAMPP/xamppfiles/apache2/htdocs"


SSLEngine on
SSLCertificateFile /Applications/XAMPP/xamppfiles/apache2/htdocs/ca.crt
SSLCertificateKeyFile /Applications/XAMPP/xamppfiles/apache2/htdocs/ca_withoutPassword.key

SSLCACertificateFile /Applications/XAMPP/xamppfiles/apache2/htdocs/ca.crt

SSLVerifyClient require

<Directory "/Applications/XAMPP/xamppfiles/apache2/htdocs">
   Options Indexes FollowSymLinks
   AllowOverride All
   Order allow,deny
   Allow from all
</Directory>

我曾尝试使用 SSLCertificateChainFile 和 SSLCACertificateFile，但没有成功。

如果我删除 'SSLVerifyClient require' 并点击服务，那么我会正确收到 authenticationMethod 'NSURLAuthenticationMethodServerTrust' 和服务器响应。

如果我在 .config 文件中添加 'SSLVerifyClient require'，则 NSURLConnection 委托方法 'willSendRequestForAuthenticationChallenge' 将调用两次，一次使用 'NSURLAuthenticationMethodServerTrust' strong> 第二次使用 'NSURLAuthenticationMethodClientCertificate' 然后我会得到上述错误。

【解决方案1】：

我认为您的 Apache 设置有误；您将 SSLCACertificateFile 指向您的客户端证书，而客户端证书应该仅在客户端；您应该将其指向您的 CA 证书。这是用于验证客户端证书的内容。

附带说明，您上面的配置真的不安全。切勿将任何 SSL 证书放在您的公共 htdocs 文件夹中。它们应该放置在只有 root 用户可以读取并且绝对远程用户无法访问的地方。这样，您将自己暴露在最严重的攻击中。
