How to create a chain keystore from a CA tree (4 levels) ?

  Asked By: Daryl    Date: Jul 14    Category: Java    Views: 1324

we need to create a key store from the following certificate tree :

Globalsign Root CA
..|_GlobalSign Primary Secure Server CA
....|_GlobalSign Secure Server CA

when I use a .cer exported from Internet Explorer, I get 3 file that
I nammed :

then I use keyStore whith the following command line to try to chain
those certs into a single keystore nammed MyCustomer :
<batch command line>
keytool -import -trustcacerts -alias GLOBALSIGN1 -file
globalsign1.cer -keypass aBcDeF -keystore MyCustomer
keytool -import -trustcacerts -alias GLOBALSIGN2 -file
globalsign2.cer -keypass aBcDeF -keystore MyCustomer
keytool -import -trustcacerts -alias GLOBALSIGN3 -file
globalsign3.cer -keypass aBcDeF -keystore MyCustomer
keytool -import -trustcacerts -alias MyCustomer -file
MyCustomerCompany.cer -keypass aBcDeF -keystore MyCustomer
</batch command line>

then I try to use this keystore in a java program (jdk 1.3.1) and all
work fine until I get the following error :
javax.net.ssl.SSLException: untrusted server cert chain

For those interested in the answer (took me over night to find :-
)... ) :

let's say you have the following tree  :

Globalsign Root CA
..|_GlobalSign Primary Secure Server CA
....|_GlobalSign Secure Server CA

then you must import all Globalsign* into cacerts and
MyCustumerCompany into a keystore

then in your code, you just specify the keystore for the SSL
implementation since Java will automatically validate higher level
from the cacerts file  (wich you can find in "%jre_home%
\lib\security\" folder)
