提问by Aniket Thakur

我是 SSL 的新手。
I am trying to create keystore for SSL connection using keytool. First I tried the following command
我正在尝试使用 keytool 为 SSL 连接创建密钥库。首先我尝试了以下命令
[aniket@localhost bin]$ keytool -genkey -alias myKeyStore -keyalg RSA -keystore
/home/aniket/keystore
It asked me password and other details and finally gave me following error
它问了我密码和其他详细信息，最后给了我以下错误
keytool error: java.io.FileNotFoundException: /home/aniket/keystore
(Is a directory)
So I created a file keystoreFile.txt inside keystore folder and executed
所以我在 keystore 文件夹中创建了一个文件 keystoreFile.txt 并执行
[aniket@localhost bin]$ keytool -genkey -alias myKeyStore -keyalg RSA -keystore
/home/aniket/keystore/keystoreFile.txt
and now(no prompt for password etc) I am getting
现在（没有提示输入密码等）我得到
keytool error: java.lang.Exception: Keystore file exists, but is empty:
/home/aniket/keystore/keystoreFile.tx
What should be the contents of the file. I though keytool will generate key pair (a public key and associated private
文件的内容应该是什么。我虽然 keytool 会生成密钥对（公钥和关联的私钥

Delete the empty keystoreFile.txt, then run your 2nd command again
删除空的 keystoreFile.txt，然后再次运行您的第二个命令
[aniket@localhost bin]$ keytool -genkey -alias myKeyStore -keyalg RSA -keystore
/home/aniket/keystore/keystoreFile.txt
It's trying to createthe file you specify with the -keystoreflag. The reason your first one command failed is that you gave it an existing directory name.
它正在尝试创建您使用-keystore标志指定的文件。你的第一个命令失败的原因是你给它一个现有的目录名。
