Android签名机制：生成keystore、签名、查看签名信息

阅读更多关于 Android签名机制：生成keystore、签名、查看签名信息

Android独有的安全机制，除了权限机制外，另外一个就是签名机制了。签名机制主要用在以下两个主要场合起到其作用：升级App和权限检查。升级App 用户在升级一款已经安装过的App时，如果程序的修改来自于同一来源，则允许升级安装，否则会提示签名不一致无法安装的提示。权限检查我曾在 Android Permission权限机制的具体使用一文中提过，对于申请权限的 protection level 为 signature 或者 signatureOrSystem 的，会检查权限申请者和权限声明者的证书是否是一致的。至于签名机制的原理及其他作用，此不详述，本文主要介绍，签名文件key的生成、用key去签名apk文件及查看签名的方法。生成keystore 创建keystore，需要用到keytool.exe (位于jdk_xx\jre\bin目录下)，具体做法如下： keytool -genkey -alias mykey -keyalg RSA -validity 40000 -keystore demo.keystore #说明： # -genkey 产生密钥 # -alias mykey 别名 mykey # -keyalg RSA 使用RSA算法对签名加密 # -validity 40000 有效期限4000天 # -keystore demo.keystore

问题 I am trying to import a certificate and a key file into the keystore but I\'m unable to do that. How can I create a keystore by importing both an existing certificate (abc.crt) and abc.key files? 回答1: The easiest is probably to create a PKCS#12 file using OpenSSL: openssl pkcs12 -export -in abc.crt -inkey abc.key -out abc.p12 You should be able to use the resulting file directly using the PKCS12 keystore type. If you really need to, you can convert it to JKS using keytool -importkeystore
