Question

How to relaod the java keystore after updating the cacerts file?

Asked by: jmurphy97

Hi,

I found a similar question on this site, but the solution is not what I am looking for.
I need to know if there is a way to reload the keystore/truststore while the JVM is running?  
I tried the following after adding the certificate to the cacerts file thinking it would force the JVM to reload the cacert file but its not working.

KeyStoreFile = System.getProperty("java.home")&"/lib/security/cacerts";
System.setProperty("javax.net.ssl.keyStore", KeyStoreFile);

When I open web page I get:
Error Message: peer not authenticated
Error Type: javax.net.ssl.SSLPeerUnverifiedException

When using ColdFusions <cfhttp> tag  for an SSL site I get:
Connection Failure

If I restart the JVM the JSP page and ColdFusion <cfhttp> tag work fine. I have been successful with using a Trust ALL TrustManager to accept all certificates but this is not very secure and will not be allowed in production. I also do not want to create a new keystore each time, since it is not a solution when using ColdFusions <cfhttp> tag which will fail on SSL connections unless the certificate is trusted. So that is why I am looking for a way to reload the keystore at runtime if possible and avoid having to notify users of a restart.

Thanks
Rick

The keytool works fine to import certificates, I need to know if there is a way to reload the cacerts file while the JVM is running. Currently I have to add the certificates and restart the JVM which requires me to notify users the site will be down.

I am afraid you cannot do that, this is a serious breach of security. The only way I can think of, it is to implement your own TrustManager and all relevant classes (SSL context etc).

Otherwise you could load the new KeyStore object into memory by using the data from the new keystore.
