Android上是否有与iOS的钥匙串等效的用户凭证? [英] Is there an equivalent to iOS's Keychain for user credentials on Android?

问题描述

在Android上有与iOS的钥匙串等效的东西吗?

Is there an equivalent to iOS's Keychain on Android?

我对 Preferences API 的理解是，该API未加密.对于我的应用程序而言，这些凭据是否可以在设备之间持久(即与 Android中类似iPhone的钥匙串?)

My understanding of the Preferences API is that it is not encrypted. For my application it doesn't matter whether these credentials are persisted across devices (i.e. a different use-case to iPhone-like Keychain in Android?)

我还查看了 KeyStore API ，但这似乎将用户凭据的实际存储留给了应用程序开发人员.

I also looked at the KeyStore API but it seems to leave the actual storage of user credentials up to the application developer.

推荐答案

简短答案，没有答案.但是您可以期望文件系统是安全的.

Short answer, there isn't one. But you can expect the filesystem to be secure.

每个应用程序都在不同的用户下运行，并且用于存储应用程序数据的文件系统受常规UNIX用户权限的保护.因此，默认情况下，每个应用程序的文件访问权限都已沙箱化.文件系统也可以被加密.

Each app operates under a different user, and the filesystem used to store app data is secured by normal UNIX user permissions. So each app's file access is sandboxed by default. The filesystem also may be encrypted.
