自检APK的签名 [英] Self-checking an APK's signature

问题描述

我想在运行时以编程方式检查 APK 的签名.我在我的开发工作站上拥有一个密钥库，所以我可以知道(不知道如何)我用来签署 APK 的公钥.

I would like to programmatically perform a check on the APK's signature at runtime. I own a keystore on my development workstation, so I could know (dunno how) the public key I'm signing an APK with.

一旦知道标牌后的公钥是什么，我想放入源代码并检查当前运行的应用程序是否与密钥匹配.

Once I know what the public key will be after signage, I would like to put in the source code and check if the currently running application matches the key.

有可能吗?如果是这样，我如何从 Eclipse 生成的密钥库中获取公钥?

Is it possible? If so, how do I obtain the public key from an Eclipse-generated keystore?

谢谢.

推荐答案

你可以试试这个，应该可以

You could try this, it should work

Signature[] sigs = getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_SIGNATURES).signatures;
    for (Signature sig : sigs)
    {
        // log the sig here
    }
