 = OpenSSL Certificate Chain
 
-Version: 0.0.0.8
+Version: 0.0.0.9
 
 
 This documentation contains the complete set of commands to create a new OpenSSL self-signed
 certificate chain with V3 subjectAltName (SAN) extensions enabled.
 Multiple SANs can be included in a certificate by adding each domain as a comma-delimited string.
 Each key can be encrypted or unencrypted, with multiple encryption options; AES is recommended.
+Optional verification can also be performed between multiple levels of certificates to ensure the
+chain of trust is valid.
