Some SSL issues (Client TLS1.2 , Truststore & SSL debug) with Solutions

For, javax.net.ssl.SSLException: SSLSocketFactory is null. This can occur if javax.net.ssl.SSLSocketFactory.getDefault() is called to create a socket and javax.net.ssl.* properties are not set.

 

1. Locate to /app/IBM/WebSphere/AppServer/java/8.0/jre/lib/security/java.security file

 

2. Add below parameters for SSL factory.

****************************************

 ssl.SocketFactory.provider=com.ibm.jsse2.SSLSocketFactoryImpl

 ssl.ServerSocketFactory.provider=com.ibm.jsse2.SSLServerSocketFactoryImpl

 ****************************************

for , Caused by: javax.net.ssl.SSLException: Received fatal alert: protocol_version while client was trying to connect with lower TLS version. 

1. locate to application JAVA_OPTIONS

2. Add below parameters for SSL for Specifying simply jdk.tls.client.protocols="TLSv1.2" will cause any type of ClientHello to use TLSv1.2 (https included). The https.protocols is only valid if the Client Application us using HttpsURLConnection class or URL.openStream() operations.

****************************************

-Dhttps.protocols=TLSv1.2

-Djdk.tls.client.protocols=TLSv1.2 

****************************************

For, Force application Controller to use TLS 1.2

1. locate to application JAVA_OPTIONS

2. Add below parameters for SSL for Specifying, To enable and force TLS 1.2 you need to append two java runtime arguments:

 ****************************************

-Dcom.ibm.jsse2.overrideDefaultTLS=true

-Dcom.ibm.jsse2.overrideDefaultProtocol=TLSv12

 ****************************************

For, JVM arguments: Client TLS1.2 , Truststore & SSL debug

1. locate to application JAVA_OPTIONS

2. Add below parameters for SSL for Client TLS1.2 , Truststore & SSL debug.

 ****************************************

-Djavax.net.ssl.trustStore=/app/IBM/WebSphere/AppServer/java/8.0/jre/lib/security/cacerts 

-Djavax.net.ssl.trustStorePassword=changeit 

-Djavax.net.ssl.trustStoreType=jks 

-Dhttps.protocols=TLSv1.2 

-Djdk.tls.client.protocols=TLSv1.2 

-Dcom.ibm.jsse2.overrideDefaultTLS=true 

-Djavax.net.debug=ssl,handshake,data,trustmanager

 ****************************************

For,javax.net.ssl.SSLHandshakeException: No subject alternative DNS name matching (javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching ip address found.) - LDAP

 1. locate to application JAVA_OPTIONS

2. Add below parameters for LDAP disableEndpointIdentification.

****************************************

-Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

****************************************
