[java] Confused about jar and self-signing
Author
Hello,
I would like put my applet up on the web and found out that I need to have my program self signed and certificates and whatnot. I was trying to search it on google for a couple days now and its all very confusing. Could someone help me out as to how I can get this to work because I am creating a demo for my porfolio and buying a certificate is too expensive for this.
I take it I need to put all me files into a jar file? Then I need to self sign it?
Are there any exclipse plug-ins to make this easier? Would Jar Compiler - v1.2.3 compiler my project into a jar file? Also I heard of EclipseNSIS Utilities - v0.9.2.2 to create certificates and sign them? Are there any other plug-ins or better plug-ins that I could use for this.
This is my first project I am uploading to the net so please excuse me if I am not getting anything right. I am just looking for an easy way to get my small game/work up on my portfolio. Thanks

keytool wont stay open. It closes after being run. When I go to cmd prompt, keytool is not recognized as a program..

It's a command line program only.

You need to set up your PATH correctly for the JDK you have installed.

So in order to do
"keytool -genkey -keyalg rsa -alias yourkey"
and follow the instuctions, I need to set up my path correctly?
I set up my patch, but then I went to cmd prompt, and typed "keytool". It still would not recognize it as a program. Do I type in "keytool -genkey -keyalg rsa -alias yourkey" into cmd prompt. I'm really confused, need help, thanks

Well, you must have done it wrong :)
Try this as an alternative: manually cd to your JDK bin directory before executing keytool.
An an example, my JDK is located at C:\Program Files\Java\jdk1.5.0_06, so I enter:
cd C:\Program Files\Java\jdk1.5.0_06\bin
keytool

Alias is a short name you give to an entry in the keystore. It's not the password. Use the same alias you gave on the -genkey line.
The command (-export) will create the crt file.

ok, i typed in "keytool -export -alias myname -file myfile.crt". Then it asked me for a password. I typed it in and it displayed "keytool error: java.io.FileNotFoundException: myfile.crt <Access is denied>". That's why I though I make a crt first. So, I don't know what to do now. Thanks for your help. I really appreciate it. :)

from the manual of keytool:
To export a certificate to a file, use the -export command, as in keytool -export -alias jane -file janecertfile.cerThis sample command exports jane's certificate to the file janecertfile.cer.Your error message says: Access Denied ... do you have permissions to write to the directory you are working in?
And just to make completely sure it works from my local machine:
C:\tmp>keytool -genkey -alias testEnter keystore password:Re-enter new password:What is your first and last name? [Unknown]: testWhat is the name of your organizational unit? [Unknown]: testWhat is the name of your organization? [Unknown]: testWhat is the name of your City or Locality? [Unknown]: testWhat is the name of your State or Province? [Unknown]: testWhat is the two-letter country code for this unit? [Unknown]: teIs CN=test, OU=test, O=test, L=test, ST=test, C=te correct? [no]: yesEnter key password for <test> (RETURN if same as keystore password):C:\tmp>keytool -export -alias test -file test.cerEnter keystore password:Certificate stored in file <test.cer>C:\tmp>dir Volume in drive C has no label. Volume Serial Number is 7C33-8EDC Directory of C:\tmp11/12/2009 10:12 AM <DIR> .11/12/2009 10:12 AM <DIR> ..06/14/2009 07:42 PM <DIR> nvid11/12/2009 10:10 AM 746 test.cer 1 File(s) 746 bytes 3 Dir(s) 48,417,484,800 bytes freeC:\tmp>Seems to work ... check permissions and try again?
