IOS相互认证 [英] IOS Mutual Authentication
问题描述
我想在iOS 5中实现相互认证,但我有麻烦:
I'm trying to implement mutual authentication in IOS 5 but i'm having troubles:
{NSUnderlyingError = "Error Domain=kCFErrorDomainCFNetwork Code=-1200 \"An SSL error has occurred and a secure connection to the server cannot be made.\" UserInfo=0x18d830 {NSLocalizedDescription=An SSL error has occurred and a secure connection to the server cannot be made., _kCFNetworkCFStreamSSLErrorOriginalValue=-9800, _kCFStreamPropertySSLClientCertificateState=0, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, NSErrorFailingURLStringKey=https://192.168.24.110:8081/t01.json, kCFStreamPropertySSLPeerTrust=<SecTrustRef: 0xceaa2d0>, NSErrorFailingURLKey=https://192.168.24.110:8081/t01.json}
我生成的密钥,证书和PKCS12服务器(无论是自签名或用假CA我总是这个问题)和客户端是这样的:
I generated keys, certificates and pkcs12 for server (either self signed or with a fake CA I always got that problem) and client this way:
openssl genrsa -out client.key 1024
openssl req -new -key client.key -out client.csr
self-signed
openssl req -new -key ca.key -x509 -days 1095 -out ca.crt
CA signed
openssl x509 -req -days 365 -in client.csr -CA server.crt -CAkey server.key -CAcreateserial -out client.crt
CRT to PEM
openssl x509 -in client.crt -out client.der -outform DER
openssl x509 -in client.der -inform DER -out client.pem -outform PEM
PEM TO PKCS 12
openssl pkcs12 -export -in client.pem -inkey client.key -out client.p12
由此产生的client.p12文件完美的作品,当我导入它在浏览器(FF15)。所以,问题不是在previous步骤找到。
The resulting client.p12 file works perfectly when I import it in the browser (FF15). So the problem is not locate in the previous steps.
IOS端我想这个例子:<一href=\"http://vanjakom.word$p$pss.com/tag/nsurlconnection/\">http://vanjakom.word$p$pss.com/tag/nsurlconnection/
IOS side I tried this example: http://vanjakom.wordpress.com/tag/nsurlconnection/
这是我写的,当我发现,例如不工作:
and this is what I wrote when I found that example not working:
// Returns an array containing the certificate
- (CFArrayRef)getCertificate:(SecIdentityRef) identity {
SecCertificateRef certificate = nil;
SecIdentityCopyCertificate(identity, &certificate);
SecCertificateRef certs[1] = { certificate };
CFArrayRef array = CFArrayCreate(NULL, (const void **) certs, 1, NULL);
SecPolicyRef myPolicy = SecPolicyCreateBasicX509();
SecTrustRef myTrust;
OSStatus status = SecTrustCreateWithCertificates(array, myPolicy, &myTrust);
if (status == noErr) {
NSLog(@"No Err creating certificate");
} else {
NSLog(@"Possible Err Creating certificate");
}
return array;
}
// Returns the identity
- (SecIdentityRef)getClientCertificate {
SecIdentityRef identityApp = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSString *myFilePath = [documentsDirectoryPath stringByAppendingPathComponent:@"file12.p12"];
NSData *PKCS12Data = [NSData dataWithContentsOfFile:myFilePath];
CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
CFStringRef password = CFSTR("password");
const void *keys[] = { kSecImportExportPassphrase };//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;
}
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
if ([challenge previousFailureCount] == 0) {
SecIdentityRef identity = [self getClientCertificate]; // Go get a SecIdentityRef
CFArrayRef certs = [self getCertificate:identity]; // Get an array of certificates
// Convert the CFArrayRef to a NSArray
NSArray *myArray = (__bridge NSArray *)certs;
// Create the NSURLCredential
NSURLCredential *newCredential = [NSURLCredential credentialWithIdentity:identity certificates:myArray persistence:NSURLCredentialPersistencePermanent];
// Send
[challenge.sender useCredential:newCredential forAuthenticationChallenge:challenge];
} else {
// Failed
[[challenge sender] cancelAuthenticationChallenge:challenge];
}
}
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
return YES;
}
在这两种情况下,我不能autheticate客户端。
而且我也装设备(iPhone / iPad的)对server.crt证书,但我不断收到错误域= NSURLErrorDomain code = -1200。
In both cases I can't autheticate the client. Moreover I also installed the server.crt certificate on the device (iPhone/iPad) but I keep receiving "Error Domain=NSURLErrorDomain Code=-1200".
任何想法?
谢谢你。
Any ideas? Thank you.
推荐答案
在code我写的作品完美,问题是服务器端。
The code I wrote works perfectly, the problem was server side.
