ios - 无法以编程方式在 iOS 上安装 .der 证书

我正在尝试以编程方式在 iOS(iPhone/iPhone 模拟器)上安装 SSL 证书。 我已经使用 this small guide 成功创建并安装了 .crt ! 但是当我尝试将获得的 server.crt 转换为 server.der 并以编程方式安装它时,我得到 CFNetwork SSLHandshake failed (-9807)。请注意,我在 iOS 上使用此证书的 .der 版本,在 OS X openssl 服务器上使用 .crt 版本。

转换:

openssl x509 -outform der -in server.crt -out server.der

在 OS X 上接收:

openssl s_server -key server.key -cert server.crt -accept 1678

在iOS上安装和发送:

    NSBundle *bundle = [NSBundle bundleForClass:[self class]];
NSData *iosTrustedCertDerData =
[NSData dataWithContentsOfFile:[bundle pathForResource:@"certificate"
ofType:@"der"]];

OSStatus err = noErr;
SecCertificateRef cert;

cert = SecCertificateCreateWithData(NULL, (CFDataRef) iosTrustedCertDerData);
assert(cert != NULL);

CFTypeRef result;

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

err = SecItemAdd((CFDictionaryRef)dict, &result);
assert(err == noErr || err == errSecDuplicateItem);

printf("adding finished \n");


if ((err == noErr) ||
(err == errSecDuplicateItem)) {

printf("success \n");

CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL,
(CFStringRef)@"localhost",
1678,
&readStream,
&writeStream);
CFReadStreamSetProperty(readStream,
kCFStreamPropertySocketSecurityLevel,
kCFStreamSocketSecurityLevelTLSv1);
CFReadStreamOpen(readStream);
CFWriteStreamOpen(writeStream);

UInt8 buf[] = "Hello from iOS\n";
int bytesWritten = CFWriteStreamWrite(writeStream, buf, strlen((char*)buf));
}

那么,如何在iOS上正确转换和安装.der证书呢?

更新:

 NSBundle *bundle = [NSBundle bundleForClass:[self class]];

NSString *resourcePath = [bundle pathForResource:@"certificate" ofType:@"der"];

NSData *certData = [NSData dataWithContentsOfFile:resourcePath];

NSString* publickKeyRef = @"certificate_der";

NSData* headerStrippedData = [self stripPublicKeyHeader:certData];
[self addPeerPublicKey:publickKeyRef keyBits:headerStrippedData];

SecKeyRef ref= [self getPublicKeyReference:publickKeyRef];

printf("adding finished \n");


CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL,
(CFStringRef)@"localhost",
1678,
&readStream,
&writeStream);
CFReadStreamSetProperty(readStream,
kCFStreamPropertySocketSecurityLevel,
kCFStreamSocketSecurityLevelTLSv1);
CFReadStreamOpen(readStream);
CFWriteStreamOpen(writeStream);

异常发生在这一行:

[self addPeerPublicKey:publickKeyRef keyBits:headerStrippedData];

异常(exception):

最佳答案

在 iOS 中,它有点不同,您需要将此 .der 文件添加到您的钥匙串(keychain),然后从您的钥匙串(keychain)引用它。我正在提供下面的代码以添加钥匙串(keychain)并从钥匙串(keychain)中取回

- (void)addPeerPublicKey:(NSString *)peerName keyBits:(NSData *)publicKeyData {

OSStatus sanityCheck = noErr;
CFTypeRef persistPeer = NULL;
[self removePeerPublicKey:peerName];

NSData * peerTag = [[NSData alloc] initWithBytes:(const void *)[peerName UTF8String] length:[peerName length]];
NSMutableDictionary * peerPublicKeyAttr = [[NSMutableDictionary alloc] init];
[peerPublicKeyAttr setObject:(id)kSecClassKey forKey:(id)kSecClass];
[peerPublicKeyAttr setObject:(id)kSecAttrKeyTypeRSA forKey:(id)kSecAttrKeyType];
[peerPublicKeyAttr setObject:peerTag forKey:(id)kSecAttrApplicationTag];
[peerPublicKeyAttr setObject:publicKeyData forKey:(id)kSecValueData];
[peerPublicKeyAttr setObject:[NSNumber numberWithBool:YES] forKey:(id)kSecReturnData];
sanityCheck = SecItemAdd((CFDictionaryRef) peerPublicKeyAttr, (CFTypeRef *)&persistPeer);

if(sanityCheck == errSecDuplicateItem)
{
NSLog(@"HanselErrorCode: -1");
}

persistPeer = NULL;
[peerPublicKeyAttr removeObjectForKey:(id)kSecValueData];
sanityCheck = SecItemCopyMatching((CFDictionaryRef) peerPublicKeyAttr, (CFTypeRef*)&persistPeer);

if (persistPeer) CFRelease(persistPeer);
}

-(SecKeyRef)getPublicKeyReference:(NSString*)peerName
{
OSStatus sanityCheck = noErr;

SecKeyRef pubKeyRefData = NULL;
NSData * peerTag = [[NSData alloc] initWithBytes:(const void *)[peerName UTF8String] length:[peerName length]];
NSMutableDictionary * peerPublicKeyAttr = [[NSMutableDictionary alloc] init];

[peerPublicKeyAttr setObject:(id)kSecClassKey forKey:(id)kSecClass];
[peerPublicKeyAttr setObject:(id)kSecAttrKeyTypeRSA forKey:(id)kSecAttrKeyType];
[peerPublicKeyAttr setObject:peerTag forKey:(id)kSecAttrApplicationTag];
[peerPublicKeyAttr setObject:[NSNumber numberWithBool:YES] forKey: (id)kSecReturnRef];
sanityCheck = SecItemCopyMatching((CFDictionaryRef) peerPublicKeyAttr, (CFTypeRef*)&pubKeyRefData);

if(pubKeyRefData)
{
return pubKeyRefData;
}
else
{
return nil;
}
}

- (NSData *)stripPublicKeyHeader:(NSData *)d_key
{
// Skip ASN.1 public key header
if (d_key == nil) return(nil);

unsigned int len = (unsigned int)[d_key length];
if (!len) return(nil);

unsigned char *c_key = (unsigned char *)[d_key bytes];
unsigned int idx = 0;

if (c_key[idx++] != 0x30) return(nil);

if (c_key[idx] > 0x80) idx += c_key[idx] - 0x80 + 1;
else idx++;

// PKCS #1 rsaEncryption szOID_RSA_RSA
static unsigned char seqiod[] =
{ 0x30, 0x0d, 0x06, 0x09, 0x2a, 0x86, 0x48, 0x86, 0xf7, 0x0d, 0x01, 0x01,
0x01, 0x05, 0x00 };
if (memcmp(&c_key[idx], seqiod, 15)) return(nil);

idx += 15;

if (c_key[idx++] != 0x03) return(nil);

if (c_key[idx] > 0x80) idx += c_key[idx] - 0x80 + 1;
else idx++;

if (c_key[idx++] != '\0') return(nil);

// Now make a new NSData from this buffer
return([NSData dataWithBytes:&c_key[idx] length:len - idx]);

}


- (void)removePeerPublicKey:(NSString *)peerName
{
OSStatus sanityCheck = noErr;

NSData * peerTag = [[NSData alloc] initWithBytes:(const void *)[peerName UTF8String] length:[peerName length]];
NSMutableDictionary * peerPublicKeyAttr = [[NSMutableDictionary alloc] init];

[peerPublicKeyAttr setObject:(__bridge id)kSecClassKey forKey:(__bridge id)kSecClass];
[peerPublicKeyAttr setObject:(__bridge id)kSecAttrKeyTypeRSA forKey:(__bridge id)kSecAttrKeyType];
[peerPublicKeyAttr setObject:peerTag forKey:(__bridge id)kSecAttrApplicationTag];

sanityCheck = SecItemDelete((__bridge CFDictionaryRef) peerPublicKeyAttr);
}

要使用此 key ,您必须执行以下操作

NSString *resourcePath = [bundle pathForResource:@"publickey" ofType:@"der"];
NSData *certData = [NSData dataWithContentsOfFile:resourcePath];

NSData* headerStrippedData = [self stripPublicKeyHeader:certData];
[self addPeerPublicKey:publickKeyRef keyBits:headerStrippedData];

SecKeyRef ref= [self getPublicKeyReference:publickKeyRef];

最后使用 ref 实现所有目的。

NSString* publickKeyRef = @"key_name_against_which_you_want_to_save_your_der";

此代码向您展示了添加、取回和使用它的方法。几个月前我从互联网上获取了这段代码——如果你找到了,请添加源代码链接。在 Xcode8 中,您必须添加钥匙串(keychain)的名称(publicKeyRef),您将在功能部分中使用此 der 文件。
