Java not providing client certificate for mutual SSL?

问题


I’m trying to connect with mutual SSL from a Java SpringBoot application to a NetScaler endpoint. I am able to connect as expected on the command line via OpenSSL with the following command:

openssl s_client -connect xxxx.xxxx.xxxx.xxx:443 -cert cert.cer -key private.key

Which gives the following output:

CONNECTED(00000003)

In order connect from the Java application I’ve combined the key and the certificate in cert.cer and private.key files with the following command:

openssl pkcs12 -export -in cert.cer -inkey private.key -out keystore.p12

I start the Spring application with the following parameters:

-Djavax.net.debug=ssl
-Djavax.net.ssl.keyStore=C:/opt/wtr-certs/keystore.p12
-Djavax.net.ssl.keyStorePassword=XXXXXXXXX

I can clearly see my keystore getting loaded as the Java application tries to connect but it seems to fail when trying to present the client certificate to the server.

Loading the keystore:

trigger seeding of SecureRandom
done seeding SecureRandom
keyStore is : C:/opt/wtr-certs/keystore.p12
keyStore type is : jks
keyStore provider is : 
init keystore
init keymanager of type SunX509
***

I believe the Java application isn't presenting the certificate correctly as shown by this section of the logs:

*** CertificateRequest

*** ServerHelloDone
Warning: no suitable certificate found - continuing without client authentication
*** Certificate chain

***

There appears to be a similar, older, question here: Java not sending client certificate but it has no answers. How can I persuade Java to find a send the correct certificate? I can provide additional logging if required.
