How to automate Keystore generation using the java

问题:

I am trying to automate keystore generation using the Java keystore tool. The command I am using is :

keytool -keystore keystore -alias jetty -genkey -keyalg RSA

But after this command, user is required to enter certain inputs as follows:

Enter keystore password:  password
What is your first and last name?  
[Unknown]:  jetty.mortbay.org  
What is the name of your organizational unit?  
[Unknown]:  Jetty  
What is the name of your organization?  
[Unknown]:  Mort Bay Consulting Pty. Ltd.  
What is the name of your City or Locality?  
[Unknown]:  
What is the name of your State or Province?  
[Unknown]:  
What is the two-letter country code for this unit?  
[Unknown]:  
Is CN=jetty.mortbay.org, OU=Jetty, O=Mort Bay Consulting Pty. Ltd.,  
L=Unknown, ST=Unknown, C=Unknown correct?  
[no]:  yes  

Enter key password for <jetty>  
(RETURN if same as keystore password):  password  

Instead of the user entering these values , is there any way of providing these values without user interaction ,either within the command or through a script?

Thanks

Try this:

keytool -genkey -noprompt \
 -alias alias1 \
 -dname "CN=mqttserver.ibm.com, OU=ID, O=IBM, L=Hursley, S=Hants, C=GB" \
 -keystore keystore \
 -storepass password \
 -keypass password

回答2:

don't forget -noprompt, otherwise you will be asked to input Yes or No

See the full documentation about command line or by typing keytool without any arguments.

Specifically you may want to look options -storepass password -keypass password
