打开本地项目钥匙扣？

问题描述

有没有人知道如何使用 SecKeychainOpen 打开Local Items钥匙串（Mavericks中的新钥匙串）？在该钥匙串中有一些条目，我想要能够请求用户使用 SecKeychainFindInternetPassword 访问的权限。

Does anyone know how to open the Local Items keychain (new in Mavericks) with SecKeychainOpen? There are certain entries in that keychain that I'd like to be able to ask the user permission to access using SecKeychainFindInternetPassword.

例如对于System keychain，您调用 SecKeychainOpen（/Library/Keychains/System.keychain，& keychainRef）。

e.g. for the System keychain you call SecKeychainOpen ("/Library/Keychains/System.keychain",&keychainRef).

推荐答案

希望这有助于：

#include <CoreFoundation/CoreFoundation.h>
#include <Security/Security.h>
#include <CoreServices/CoreServices.h>    
#include <iostream>

using namespace std;

int main (int argc, char** argv)
{
    OSStatus status;
    SecKeychainRef targetKeychain;
    SecKeychainRef originKeychain;
    SecKeychainRef newKeychain;

    status = SecKeychainCreate("example.keychain", 4, "1234", false, NULL, &targetKeychain);
    if(errSecDuplicateKeychain == status)
        status = SecKeychainOpen("example.keychain", &targetKeychain);
    cerr << "Create/Open keychain -- " << status << endl;

    status = SecKeychainCopyDefault(&originKeychain);
    cerr << "Get default keychain -- " << status << endl;

    status = SecKeychainSetDefault(targetKeychain);
    cerr << "Set default keychain -- " << status << endl;

    status = SecKeychainCopyDefault(&newKeychain);
    char pathName[256] = {0};
    UInt32 pathLength = 256;
    status = SecKeychainGetPath(newKeychain, &pathLength, pathName);
    cerr << "New default keychain at path " << pathName << endl;

    status = SecKeychainSetDefault(originKeychain);
    cerr << "Set default keychain back -- " << status << endl;

    status = SecKeychainCopyDefault(&newKeychain);
    memset(pathName, 0, pathLength);
    status = SecKeychainGetPath(newKeychain, &pathLength, pathName);
    cerr << "Now default keychain at path " << pathName << endl;

    return 0;
}
