FAQ/subjectAltName (SAN) What is subjectAltName? SubjectAltName specifies additional subject identities, but for host names (and everything else defined for subjectAltName): subjectAltName must always be used (RFC 3280 4.2.1.7, 1. Dec 02, 2018 Reduce SSL cost and maintenance by using a single certificate for multiple websites using SAN certificate. SAN stands for “Subject Alternative Names” and this helps you to have a single certificate for multiple CN (Common Name). You might be thinking this is wildcard SSL but let me tell you – it’s slightly different. In SAN certificate, you can have multiple complete CN.

As of OpenSSL 1.1.1, providing subjectAltName directly on command line becomes much easier, with the introduction of the -addext flag to openssl req (via this commit).
1.8.5 SSL SecurityWarning: Certificate has no subjectAltName
When you configure a Ceph Object Gateway instance and enable SSL you must create an SSL certificate. If the certificate does not have the v3 extension enabled and the subjectAltName set within the certificate, a warning message is displayed when a client such as the Swift client attempts to access the gateway:
If a
subjectAltName
extension of type dNSName
is present, this is used as the identity. Otherwise, the Common Name
field in the Subject
field of the certificate is used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead. To prevent the warning from appearing at all, do the following:
- In the working directory where you are generating the key and certificate, create a copy of the template OpenSSL configuration file:
- Modify the configuration file template at
./openssl.cnf
and make the following changes:- In the section
[ req ]
make sure that the following line is uncommented and not preceded with a # character: - In the section
[ v3_req ]
, add the following line to the end of the parameters in this section: - Add a section to the end of the configuration file:Replace
hostname.example.com
with the fully qualified domain name for the host that you are creating the certificate for.
- Generate your certificate key, as normal:
- Use the certificate key and the new
openssl.cnf
file to create a Certificate Signing Request (CSR): - You may either use the generated CSR to obtain a signed certificate from a recognized Certificate Authority (CA). Or, for testing purposes, you may use this to generate a self-signed certificate as follows:
- Create a new configuration file,
v3.cnf
, that can host the information for the v3 requirements. Edit it to contain the following lines: - Run the following OpenSSL command to generate a self-signed certificate using the CSR and your local key:
- Copy the key, CSR and certificate to the usable location on the host:
- Create a single PEM file containing both the key and certificate, that can be used by the Ceph Object Gateway when it is started:

The machine SSL certificate is used by the reverse proxy service on every management node, Platform Services Controller, and embedded deployment. Each machine must have a machine SSL certificate for secure communication with other services. You can replace the certificate on each node with a custom certificate.
Linux Generate Ssl Key With Subjectaltname Key
Before you start, you need a CSR for each machine in your environment. You can generate the CSR using vSphere Certificate Manager or explicitly.
- To generate the CSR using vSphere Certificate Manager, see Generate Certificate Signing Requests with vSphere Certificate Manager (Custom Certificates).
- To generate the CSR explicitly, request a certificate for each machine from your third-party or enterprise CA. The certificate must meet the following requirements:
- Key size: 2048 bits or more (PEM encoded)
- CRT format
- x509 version 3
- SubjectAltName must contain DNS Name=<machine_FQDN>
- Contains the following Key Usages: Digital Signature, Non Repudiation, Key Encipherment

Procedure
- Start vSphere Certificate Manager and select option 1.
- Select option 2 to start certificate replacement and respond to the prompts. Word product key free. vSphere Certificate Manager prompts you for the following information:
- Password for [email protected].
- Valid Machine SSL custom certificate (.crt file).
- Valid Machine SSL custom key (.key file).
- Valid signing certificate for the custom machine SSL certificate (.crt file).
- If you are running the command on a management node in a multi-node deployment, IP address of the Platform Services Controller.
Depending on your environment, you might have to replace additional certificates explicitly.
- If company policy requires that you replace all certificates, replace the vmdir root certificate.
