Generate trusted local SSL cert for Solr
# Usage:
# This script is designed to be run after you have Solr running locally without SSL
# It will generate a trusted, self-signed certificate for LOCAL DEV (this must be modified for production)
# Notes: The keystore must be under server/etc on Solr root, and MUST be named solr-ssl.keystore.jks
# The cert will be added to locally trusted certs, so no security warnings in browsers
# You must still reconfigure Solr to use the keystore and restart it after running this script
#
# THIS SCRIPT REQUIRES WINDOWS 10 (for the SSL trust); without 10 remove the lines around trusting the cert.

For Solr 8.8.2 (required for Sitecore 10.2), I had to add the following to the solr.in.cmd file. Without those lines, I was getting the error "java.io.IOException: DerInputStream.getLength(): lengthTag=109, too big."

set SOLR_SSL_KEY_STORE_TYPE=jks set SOLR_SSL_TRUST_STORE_TYPE=jks

thank you so much for this! and thanks to OP, amazing job!
