keytool error: java.lang.Exception: The -keyalg option must be specified

Question

我在 Windows 10 Administrator 中生成我的 android 应用程序证书，这是我为我的应用程序生成证书时输入的命令。

keytool -genkey -v -keystore c:\my-release-key.keystore -alias omar

如图所示，您也可以看到错误。但是很抱歉，我是 Android 的新手，这是我第一次创建证书。非常感谢帮助。

错误是keytool error: java.lang.Exception: The -keyalg option must be specified

密码=“123456”
