Unable to access HTTPS service using Spring Rest Template - TrustStore issue? - spring

Question

While accessing a HTTPS service I am facing the below issue :
Error:
..Certification authentication failed</TITLE>
...
An attempt to authenticate with a client certificate failed.
A valid client certificate is required to make this connection.
I am using Spring RestTemplate excahnge API :
restTemplate.exchange(reqInfo.getUrl(),HttpMethod.GET,requestEntity,String.class);
I tried 2 methods to provide the trustStore but still the error persists:
1.) Passing as arguments :
java -cp -Djavax.net.ssl.trustStore="trustStore.jks"
-Djavax.net.ssl.trustStorePassword="pwd" Test
2.) Setting the property
System.setProperty("javax.net.ssl.trustStore","path to truststore");
System.setProperty("javax.net.ssl.trustStorePassword","pwd");
Also I tried with simple Java code using HTTPclient then it works fine but with SPring RestTemplate none of option is working , am i missing something here ?
Note : If I do curl of that URL I get the same error as truststore is not provided . Hence I am assuming that this issue is due to TrustStore.

Answer 1

Finally I was able to solve the above issue .
While building the SSL context I did not load the key store ( although I was passing it via arguments) due to which I was getting Certification authentication failed as the Key store was not available .
Below code fixed the issue : (added loadKeyMaterial )
sslcontext = SSLContexts.custom().loadTrustMaterial(trustStore, new TrustSelfSignedStrategy())
.loadKeyMaterial(keyStore, keyStorePwd).build();
