SafetyNet 认证中是否需要 api 密钥? [英] Is api key needed in SafetyNet attestation?

问题描述

我已成功为 SafetyNet 证明创建了后端服务和 Android 客户端.当我将 jws 令牌发送到我的服务器并尝试验证它的证书时，结果发现没有对其进行签名的证书.

我应该将 api 密钥添加到我的 Android 应用程序中吗?

解决方案

您需要在最新版本的 Google Play 服务中使用 API 密钥.

请参阅有关新的文档 SafetyNetClient::attest(byte[], String) 方法.

<小时>

作为旁注，我强烈建议您在此处为 Android 应用生成的密钥的验证配额设置为最小值 1:

https://console.developers.google.com/projectselector/apis/api/androidcheck.googleapis.com/quotas

这(几乎是 1 个错误；))阻止攻击者使用可以从您的客户端代码中检索的密钥，如下所示:

解决方案

You are required to use API key with the latest version of Google Play Services.

See documentation on new SafetyNetClient::attest(byte[], String) method.

---

As a side note I highly recommend to set the verification quota to minimal value of 1 for a key you generate for your Android app here:

https://console.developers.google.com/projectselector/apis/api/androidcheck.googleapis.com/quotas

This (almost, off by 1 error ;)) stops an attacker from using a key which can be retrieved from your client code like so:
