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.

$ openssl genrsa -out private.key 3072 $ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730 You are about to be asked to enter information that will be incorporated into your certificate request.

• Create the certificate key openssl genrsa -out mydomain.com.key 2048 Create the signing (csr) The certificate signing request is where you specify the details for the certificate you want to generate. This request will be processed by the owner of the Root key (you in this case since you create it earlier) to generate the certificate.

• May 02, 2016  Generating a CSR with SAN at the command line. Lately, I’ve explored creating my own CSRs for use with Let’s Encrypt, so I can control the common name and subject names. Including additional domains, a technique known as Subject Alternatives Names or subjectAltName (SAN). In /etc/ssl/openssl.cnf, you may need to uncomment this line.

Before you start, you need a CSR for each machine in your environment. You can generate the CSR using vSphere Certificate Manager or explicitly.

1. To generate the CSR using vSphere Certificate Manager, see Generate Certificate Signing Requests with vSphere Certificate Manager (Custom Certificates).

2. 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

See also VMware Knowledge Base article 2112014, Obtaining vSphere certificates from a Microsoft Certificate Authority.

Procedure

1. Start vSphere Certificate Manager and select option 1.
2. Select option 2 to start certificate replacement and respond to the prompts.

   Generate rsa key pair tool. vSphere Certificate Manager prompts you for the following information:

   • Password for administrator@vsphere.local.

   • 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. See Replace the VMware Directory Service Certificate

• If you are upgrading from a vSphere 5.x environment, you might have to replace the vCenter Single Sign-On certificate inside vmdir. See Replace the VMware Directory Service Certificate in Mixed Mode Environments

The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.

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:

1. In the working directory where you are generating the key and certificate, create a copy of the template OpenSSL configuration file:

2. 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.

3. Generate your certificate key, as normal:

4. Use the certificate key and the new openssl.cnf file to create a Certificate Signing Request (CSR):

5. 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:

6. Copy the key, CSR and certificate to the usable location on the host:

7. Create a single PEM file containing both the key and certificate, that can be used by the Ceph Object Gateway when it is started:
