I had to create a SAN cert. If you google you will find a lot of articles telling you to modify your openssl.cfg . You can also do it with a command. I put some special characters in the command because they need to be escaped. You can see below how:

req -newkey rsa:2048 -keyout new_private.key -sha256 -subj "/C=NL/ST=Noord-Holland/L=\'s\-Hertogenbosch/O=Your Organization/OU=I\&CT/CN=common_name.nl/subjectAltName=DNS.1=alternate_name" -out new_certificate_request.csr

You can specify more alternate names by adding more entries:


DNS.2=alternatename2
DNS.3=alternatename3

etc

A little article about Certificate requesting and processing with OpenSSL.

In this topic I hope to give a little information about certificates, PFX files and how to export them into other formats. A lot of applications require a certificate in some format (encrypted or not) to encrypt their datastream. In this topic I’m going to to cover how to create a PFX file. A PFX file is an encrypted file that contains both your public and your private key, and is password protected. I’m not going to cover how pki works, but just click this link or use Google and you’ll find all the information you need.
