NSString *path = [[NSBundle bundleForClass:[self class]]    
                    pathForResource:@"MyPrivateKey" ofType:@"p12"];
NSData *p12data = [NSData dataWithContentsOfFile:path];
if (![self getPrivateKeyRef]) 
    RSAPrivateKey = getPrivateKeywithRawKey(p12data);

>导入P12私钥

SecKeyRef getPrivateKeywithRawKey(NSData *pfxkeydata)
{ 
    NSMutableDictionary * options = [[[NSMutableDictionary alloc] init] autorelease];

    // Set the public key query dictionary
    //change to your .pfx  password here 
    [options setObject:@"MyPassword" forKey:(id)kSecImportExportPassphrase];

    CFArrayRef items = CFArrayCreate(NULL,NULL);

    OSStatus securityError = SecPKCS12Import((CFDataRef) pfxkeydata,(CFDictionaryRef)options,&items);

    CFDictionaryRef identityDict = CFArrayGetValueAtIndex(items,0);
    SecIdentityRef identityApp =
    (SecIdentityRef)CFDictionaryGetValue(identityDict,kSecImportItemIdentity);
    //NSLog(@"%@",securityError);

    assert(securityError == noErr);
    SecKeyRef privateKeyRef;
    SecIdentityCopyPrivateKey(identityApp,&privateKeyRef);

    return privateKeyRef;

}

认为没有错误(OSStatus值为0),但是items数组没有获取任何身份数据.我想知道如果我没有得到正确的p12文件格式由于OpenSSl使用错误.有没有人成功导入p12文件？我已经在这个问题上停留了几天,请给我建议,如果你有线索,谢谢！
