列出android上安装的所有证书
我正在编写一个应用程序，其中列出了安装在上的所有证书 这个装置。但我发现有两个地方有证书 存储的数据包括：列出android上安装的所有证书,android,certificate,Android,Certificate,我正在编写一个应用程序，其中列出了安装在上的所有证书 这个装置。但我发现有两个地方有证书 存储的数据包括： System/etc/security/cacerts.bks：此文件包含所有 预装证书。我可以使用 框架中定义的密钥库类/ base/keystore/java/android/security 数据/misc/keystore：安装证书的另一种方法（例如通过 certinstaller应用程序）安装第三方证书并生成 它在这个目录中的条目 但我不知道如何读取SerialNumber之类的
IssuerDN等。当我查看/etc/security/cacerts时，我看到了存储为ASCII测试的所有证书的列表。您要求的参数、SerialNumber和Issuer info存储为文本。只需将其作为文本文件打开，并读入您要查找的字符串

对于我和运行10.7.5的Mac以及随附的JavaVM+keytool，Shashwat Shriparv描述的过程略有不同：
adb pull /system/etc/security/cacerts.bks cacerts.bks
wget http://bouncycastle.org/download/bcprov-jdk16-141.jar
keytool -list -v -keystore cacerts.bks -storepass "" -storetype BKS -providerclass org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath ./bcprov-jdk16-141.jar
