Java KeyStore generating KeyStore files with commands

1. Generate the KeyStore file
Execute the following command at the command line:
Shell Code Collection Code

keytool -genkey -validity 36000 -alias www.zlex.org -keyalg RSA -keystore d:\zlex.keystore  

which
-genkey indicates that the key is generated
-validity Specify the certificate validity period, here is 36,000 days
-ALIAS Specifies the alias, this is www.zlex.org
-KEYALG Specifies the algorithm, here is the RSA
-keystore Specify the storage location, this is D:\zlex.keystore

The password I used here is 123456.

Console output:
Console Code Collection code

输入keystore密码：  再次输入新密码:  您的名字与姓氏是什么？    [Unknown]：  www.zlex.org  您的组织单位名称是什么？    [Unknown]：  zlex  您的组织名称是什么？    [Unknown]：  zlex  您所在的城市或区域名称是什么？    [Unknown]：  BJ  您所在的州或省份名称是什么？    [Unknown]：  BJ  该单位的两字母国家代码是什么    [Unknown]：  CN  CN=www.zlex.org, OU=zlex, O=zlex, L=BJ, ST=BJ, C=CN 正确吗？    [否]：  Y  输入<tomcat>的主密码          （如果和 keystore 密码相同，按回车）：  再次输入新密码:  

At this point, a Zlex.keystore file is generated under the D drive.

2. Generate a self-signed certificate
Light has KeyStore file is not enough, also need certificate file, certificate is directly provided to the outside public key credentials.
To export a certificate:
Shell Code Collection Code

keytool -export -keystore d:\zlex.keystore -alias www.zlex.org -file d:\zlex.cer -rfc  

which
-export specified as an export operation
-keystore Specifying KeyStore files
-alias specifying an alias in the export KeyStore file
-file pointing to the export path
-RFC output in text format, i.e. output in BASE64 encoding
The code here is 123456.

Console output:
Console Code Collection code

输入keystore密码：  保存在文件中的认证 <d:\zlex.cer>
