android系统key文件生成keystore

ls android/build/target/product/security

Android.mk  media.x509.pem  platform.x509.pem  releasekey.x509.pem  shared.x509.pem  testkey.x509.pem  verity.pk8
media.pk8   platform.pk8    README             shared.pk8           testkey.pk8      verity_key        verity.x509.pem

以常用的platform签名为例：

• openssl pkcs8 -inform DER -nocrypt -in platform.pk8 -out platform.pem

• openssl pkcs12 -export -in platform.x509.pem -out platform.p12 -inkey platform.pem -password pass:android -name androiddebugkey

• keytool -importkeystore -deststorepass android -destkeystore ./platform.keystore -srckeystore ./platform.p12 -srcstoretype PKCS12 -srcstorepass android

最终的platform.keystore即为我们所要的keystore
