从Flutter APK提取SHA密钥时出现错误求助

问题详情 #

为上传至Firebase获取SHA密钥，执行命令：

keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore

出现以下异常：

keytool error: java.io.IOException: Integrity check failed: java.security.NoSuchAlgorithmException: Algorithm HmacPBESHA256 not available

解决方法 #

• 使用Android SDK自带的JDK执行命令：
  直接调用Android SDK目录下的keytool（路径通常为~/Android/Sdk/jre/bin/keytool），规避系统默认JDK的兼容性问题：

  ~/Android/Sdk/jre/bin/keytool -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore
  

• 切换到OpenJDK 8版本：
  若系统默认是高版本OpenJDK，安装并切换到OpenJDK 8：

  sudo apt-get install openjdk-8-jdk
  sudo update-alternatives --config java
  sudo update-alternatives --config keytool
  

  在弹出的选项中选择OpenJDK 8对应的条目，之后重新执行原始keytool命令。
• 重新生成debug keystore：
  若旧keystore存在兼容性问题，重新生成一个：

  keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -keyalg RSA -keysize 2048 -validity 10000
  

  生成完成后再次执行获取SHA密钥的命令。
