在C＃中創建的RSA公鑰不保存在iPhone鑰匙串

Question

我試圖從C＃服務器發送RSA公鑰到iPhone，所以我可以在iPhone上加密信息並在C＃服務器中解密。但是，當我在iPhone中保存收到的公鑰時，它不會被保存。 我C＃創建關鍵是這樣的：

RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(1024); 
byte [] body = rsa.exportCspBlob(false); 

在iPhone上我使用蘋果SecKeyWrapper類代碼：

NSString *peerName = [NSString stringWithFormat:@"%@%@",peerNamePrefix, serverID ]; 
NSData * peerTag = [[NSData alloc] initWithBytes:(const void *)[peerName UTF8String] ength:[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:publicKey forKey:(id)kSecValueData]; 
[peerPublicKeyAttr setObject:[NSNumber numberWithBool:YES] forKey:(id)kSecReturnPersistentRef]; 

sanityCheck = SecItemAdd((CFDictionaryRef) peerPublicKeyAttr, (CFTypeRef *)&persistPeer); 

此操作sanityCheck爲0後，這是確定的。但是：

peerKeyRef = [self getKeyRefWithPersistentKeyRef:persistPeer]; 

返回0x0在peerKeyRef和密鑰不保存。

- (SecKeyRef)getKeyRefWithPersistentKeyRef:(CFTypeRef)persistentRef 
{ 
OSStatus sanityCheck = noErr; 
SecKeyRef keyRef = NULL; 

LOGGING_FACILITY(persistentRef != NULL, @"persistentRef object cannot be NULL."); 

NSMutableDictionary * queryKey = [[NSMutableDictionary alloc] init]; 

// Set the SecKeyRef query dictionary. 
[queryKey setObject:(id)persistentRef forKey:(id)kSecValuePersistentRef]; 
[queryKey setObject:[NSNumber numberWithBool:YES] forKey:(id)kSecReturnRef]; 

// Get the persistent key reference. 
sanityCheck = SecItemCopyMatching((CFDictionaryRef)queryKey, (CFTypeRef *)&keyRef); 
[queryKey release]; 

return keyRef; 
}

從MSDN頁：

的ExportCspBlob方法返回一個包含關鍵信息 與非託管 Microsoft加密API

所以我認爲你有兼容的 BLOB沒有理由期待iPhone軟件瞭解它。

您可以用海toxml用於更多的成功（）
