将钥匙添加到钥匙链项目

Question

所以这是我关于 Stack Overflow 的第一个问题，它是关于钥匙串的，所以，我阅读了关于钥匙串的苹果文档，他们提到可以通过其他方式生成或获取密钥“这是我的情况”，然后我创建了“查询字典“就像他们说的那样，但是当我尝试添加它时出现错误并且我的 status 等于 -50 我不知道这意味着我试图存储密钥的原因所以我可以将它与 "SecKeyDecrypt" 一起使用来解密需要 SecKey 作为参数的消息

更新：我发现返回码是什么意思 -50 errSecParam 这意味着 “传递给函数的一个或多个参数无效。” 然后我尝试删除我的 kSecValueRef as String: privateKey 它可以工作，但我仍然希望存储该密钥？？

 let privateKey = "myKey"

    let tag = "mybunlde.com".data(using: .utf8)!

        let addPrivateKey: [String: Any] = [kSecClass as String: kSecClassKey,
                                            kSecAttrApplicationTag as String: tag,
                                            kSecValueRef as String: privateKey]
        let status = SecItemAdd(addPrivateKey as CFDictionary, nil)
        guard status == errSecSuccess else { print("error while creating the key")
            return
        }

        let getPrivateKey: [String: Any] = [kSecClass as String: kSecClassKey,
                                            kSecAttrApplicationTag as String: tag,
                                            kSecAttrKeyType as String: kSecAttrKeyTypeRSA,
                                            kSecReturnRef as String: true]

        print("getPrivateKey \(getPrivateKey)")
    } else {
        print("no key found ")
    }

您可以使用这个库来存储和检索钥匙串中的数据 https://github.com/jrendel/SwiftKeychainWrapper

例如

let save: Bool = KeychainWrapper.standard.set("hello keychain", forKey: "key_name")
let get: String? = KeychainWrapper.standard.string(forKey: "key_name")
