If there are any SANs, the CN should be ignored (although some implementations will be more tolerant). The CN is only a fallback solution when no SANs are present.

This certificate should be valid for my. and but not bar.com. Regarding your second example: ' CN:bar.com, SANs: DNS:my., DNS:'. If I remember correctly, some implementations go further than this and have a list domains that would be too broad for second-level domains too (e.g.co.uk). This may seem inconvenient, but CAs make mistakes once in a while, and having a measure to prevent a potential rogue cert issued to *.com to work isn't necessarily a bad thing. Mac OS X Server 10.5.8 I just upgraded from a self-signed cert to a cert from StartCom, which requires use of an intermediate certificate on the server. This is indeed to prevent too broad cases like *.com. I'm not sure whether there's a specification to say how many minimum labels there should be, but the Chromium code indicates that there must be at least 2 dots: Label in the presented identifier, the client SHOULD NOT compareĪgainst anything but the left-most label of the reference

If the wildcard character is the only character of the left-most Left-most label (e.g., do not match bar.*.).Ģ. Which the wildcard character comprises a label other than the The client SHOULD NOT attempt to match a presented identifier in The specifications ( RFC 6125 and RFC 2818 Section 3.1) talk about ' left-most' labels, which implies there should be more than one label: 1. If you followed the steps above, enter the following command to create the SSL certificate using the csr file.The problem is that you're trying to use too broad a wildcard ( * or *.com). So, let's go ahead and create the self-signed certificate. In a production environment you would submit the certificate request (csr) file to the certificate authority, who would then provide you with the SSL certificate. However, there is no need to purchase a SSL certificate for local development. Voltron Data takes aim at data management with Apache Arrow.

This certificate has no authority, and I will get a warning from my browser indicating this. you can also use a self-signed certificate created by OS X Server to encrypt traffic. However, on my local development environment I am going to create a self-signed certificate. This next step is not required in a production environment. The FQDN, or fully qualified domain name, must match the website URL.

So, enter whatever suits you - except for Common Name (e.g. $ sudo openssl req -new -key -out Īfter executing this command, you will be prompted to enter information about the entity/organization/company.Īs this is a self-signed certificate, this doesn't really matter.
