iOS - 以编程方式安装SSL证书

Question

我正在编写一个phonegap插件,可以在app keychain中安装CA根证书和用户证书.

以下是用于安装证书的代码:

NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:certpath];
CFDataRef inPKCS12Data = (CFDataRef)PKCS12Data;
CFStringRef password = (CFStringRef)certPassword;
const void *keys[] = { kSecImportExportPassphrase };
const void *values[] = { password };
CFDictionaryRef optionsDictionary = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
OSStatus securityError = SecPKCS12Import(inPKCS12Data, optionsDictionary, &items);
if (securityError == 0) {
    NSLog(@" *** Certificate install Success ***");
} else {
    NSLog(@" *** Certificate install Failure ***");
}

上面的代码工作正常(securityError等于0).但是,我正在获取这些错误:

unknown apsd[59] <Warning>: <APSCourier: 0xee1ba80>: Stream error occurred for <APSTCPStream: 0x126940>: TLS Error Code=-9844 "peer dropped connection before responding"
unknown securityd[638] <Error>: CFReadStream domain: 12 error: 8

这表示设备不接受已安装的证书,因此我想知道证书未针对设备上安装的CA根证书进行验证.

我是否必须为应用程序安装CA根证书？

有任何想法吗 ？

PS:我是Objective-C和XCode环境的新手.

编辑:

以下代码用于在钥匙串中存储CA根证书:

NSString *rootCertPath = [[NSBundle mainBundle] pathForResource:@"rootca" ofType:@"cer"];
NSData *rootCertData = [NSData dataWithContentsOfFile:rootCertPath];

OSStatus err = noErr;
SecCertificateRef rootCert = SecCertificateCreateWithData(kCFAllocatorDefault, (CFDataRef) rootCertData);

CFTypeRef result;

NSDictionary* dict = [NSDictionary dictionaryWithObjectsAndKeys:
(id)kSecClassCertificate, kSecClass,
rootCert, kSecValueRef,
nil];

err = SecItemAdd((CFDictionaryRef)dict, &result);

if( err == noErr) {
    NSLog(@"Install root certificate success");
} else if( err == errSecDuplicateItem ) {
    NSLog(@"duplicate root certificate entry");
} else {
    NSLog(@"install root certificate failure");
}

似乎证书没有发送到服务器.我认为每次发出https请求时我都必须手动发送证书...我正在寻找一种方法来捕获phonegap中的每个https呼叫.

将证书导入钥匙串是不够的.新的根证书也受到用户或系统的信任.

假设您仍然拥有SecCertificateRef变量certificate,请使用以下代码来提高信任级别:

NSDictionary *newTrustSettings = @{(id)kSecTrustSettingsResult: [NSNumber numberWithInt:kSecTrustSettingsResultTrustRoot]};
status = SecTrustSettingsSetTrustSettings(certificate, kSecTrustSettingsDomainUser, (__bridge CFTypeRef)(newTrustSettings));
if (status != errSecSuccess) {
    NSLog(@"Could not change the trust setting for a certificate. Error: %d", status);
    exit(0);
}

更改信任级别将在弹出窗口中询问用户是否接受更改.
