我想添加一个私有密钥插入iOS钥匙串。 证书(公钥)工作正常,但私钥拒绝......我完全糊涂了,为什么下面的代码无法正常工作。
首先我检查如果当前密钥(=,所述钥匙链的情况下,密钥是键/值存储)是钥匙串“自由”。 然后,我要补充的私钥。
CFStringRef labelstring = CFStringCreateWithCString(NULL, [key cStringUsingEncoding:NSUTF8StringEncoding], kCFStringEncodingUTF8);
NSArray* keys = [NSArray arrayWithObjects:(__bridge id)kSecClass,kSecAttrLabel,kSecReturnData,kSecAttrAccessible,nil];
NSArray* values = [NSArray arrayWithObjects:(__bridge id)kSecClassKey,labelstring,kCFBooleanTrue,kSecAttrAccessibleWhenUnlocked,nil];
NSMutableDictionary* searchdict = [NSMutableDictionary dictionaryWithObjects:values forKeys:keys];
CFRelease(labelstring);
NSMutableDictionary *query = searchdict;
CFTypeRef item = NULL;
OSStatus error = SecItemCopyMatching((__bridge_retained CFDictionaryRef) query, &item);
if (error)
{
NSLog(@"Error: %ld (statuscode)", error);
}
if(error != errSecItemNotFound)
{
SecItemDelete((__bridge_retained CFDictionaryRef) query);
}
[query setObject:(id)data forKey:(__bridge id)kSecValueData];
OSStatus status = SecItemAdd((__bridge_retained CFDictionaryRef) query, &item);
if(status)
{
NSLog(@"Keychain error occured: %ld (statuscode)", status);
return NO;
}
调试输出如下:
2012-07-26 15:33:03.772 App[15529:1b03] Error: -25300 (statuscode)
2012-07-26 15:33:11.195 App[15529:1b03] Keychain error occured: -25299 (statuscode)
第一错误代码-25300
表示errSecItemNotFound
。 因此,有没有存放该键值。 然后,当我尝试添加专用钥匙插入钥匙串,我得到-25299
这意味着errSecDuplicateItem
。 我不明白。 这究竟是为什么?
有没有人有这样的线索或提示?
苹果的错误代码:
errSecSuccess = 0, /* No error. */
errSecUnimplemented = -4, /* Function or operation not implemented. */
errSecParam = -50, /* One or more parameters passed to a function where not valid. */
errSecAllocate = -108, /* Failed to allocate memory. */
errSecNotAvailable = -25291, /* No keychain is available. You may need to restart your computer. */
errSecDuplicateItem = -25299, /* The specified item already exists in the keychain. */
errSecItemNotFound = -25300, /* The specified item could not be found in the keychain. */
errSecInteractionNotAllowed = -25308, /* User interaction is not allowed. */
errSecDecode = -26275, /* Unable to decode the provided data. */
errSecAuthFailed = -25293, /* The user name or passphrase you entered is not correct. */
提前致谢!
更新#1:我已经想通了,它仅适用于第一次。 即使数据和关键是不同的,后第一次存入钥匙串我不能存储的其他密钥。
