Documentation - OpenSSL Self-signed Certificate Chain

-

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 (aes128 or aes256) - is recommended. Optional verification can also be performed between multiple levels of - certificates to ensure the chain of trust is valid.
