How do you know if a CSR is valid?
You can check to see if the CSR you generated is valid before trying to activate the SSL certificate. You can do so using an online tool from Namecheap or CSR checker from Comodo (now Sectigo).
Is Java a Keytool?
Introduction. Keytool is a certificate management utility included with Java. It allows users to create a single store, called a keystore, that can hold multiple certificates within it.
Where is Java Keytool located?
keytool is a tool to manage (public/private) security keys and certificates and store them in a Java KeyStore file (stored_file_name. jks). It is provided with any standard JDK / JRE distributions. You can find it under the following folder %JAVA_HOME%\bin .
Is Subject Alternative Name mandatory?

Can you use keytool to generate CSR in Tomcat?
You are not supposed to use keytool to generate a CSR in this approach. You do all the certificate wrangling with OpenSSL and just convert its result to a Java keystore to use with tomcat. – fuero Mar 31 ’13 at 15:33 To verify the CSR has the SAN subject alternative names embedded, use the keytool to print the CSR:
How to include a subject alternative name in keytool?
If you’re using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.
How to verify the CSR has the San Subject Alternative names embedded?

How to issue a CSR with a San attribute in Java?
Java’s keytool creates a keypair in the form of a self-signed certificate in the key store, and the SAN attribute goes into that self-signed certificate. If you want to issue a CSR with a SAN attribute, you need to pass the same -ext argument to ‘keytool -certreq’.
