Solution:

Please find below the commands that can be used to create the keystore and corresponding CSR request with SAN included:

Keystore creation

keytool -genkey -alias <your_alias_name> or [Domain Name] -keyalg RSA -keysize 2048 -sigalg SHA256withRSA -keystore sdp.keystore -ext san=dns:<fqdn>

CSR creation

keytool -certreq -alias <your_alias_name> -sigalg SHA256withRSA -file key.csr -keystore sdp.keystore  -ext san=dns:<fqdn>
