Using openssl to test an SSL connection with a CA file, pulled out from a Java keystore

Java, do you trust me? 🤔

Using openssl to test an SSL connection to google.com, using a CA file that's been pulled out from a Java keystore. For those days when you want to verify that you've got the right certificate in the store:

  1. Download the Equifax root certificate (which is the root CA for Google)
  2. Import the certificate into a new Java keystore
  3. Export the certificate back out again
  4. Convert the certificate to PEM
  5. Use openssl to test an SSL connection to Google with that cert
