Finally, it lists the policy for certification revocation lists. It described the folder structure within the ca directory, the location of support files for the CA, as well as properties of the signed certificates (duration, restricted usage) as well as the policy for the name ('distinguished name') of signed certificates. We only use it in conjunction with the openssl ca command. In our setup, ca-sign.cnf contains the configuration for signing certificates. (roughly equivalent to easy-rsa/clean-all)Д¬reate configuration files.

If you are some paranoid whacko serious about security, you should not run these commands on the same machine, but run commands in the server, client1, and client2 directory of respectively the server and client machines, and run commands in the CA directory on a machine that is not connected to the Internet. crt), certificate revokations ( crl), and private keys ( ca.key). This is a compromise between the completely flat file structure of easy-rsa, and the recommendations set forth by most CA tutorials, which creates directories for certificate requests (.

I'll use these directories to denote the files that are required on different host: Server only during certificate generationД¬lient 1 only during certificate generationД¬lient 2 only during certificate generation However, doing so requires a security hygiene which may not be required for a small-scale deployment. This article is partly based on the excellent tutorial by Phil Dibowitz on creating an CA.Д¬ertificates, when deployed correctly, are much more secure than passwords, since the secret (key) does not need to be exchanged or shared between the different hosts. This article describes the steps taken by easy-rsa in more detail, but basically gives the same result. The easiest method it to use easy-rsa, as described in the OpenVPN How-to. You either need to set up your own certificate infrastructure, or limit OpenVPN to use password-based authentication (see the options auth-user-pass-verify, client-cert-not-required and username-as-common-name).

You can not use an existing public key infrastructure you would allow anyone with a certificate of that PKI to connect to your server (the tls-remote and tls-verify options can limit the allowed clients). Part of configuring OpenVPN involves the creation of a certificate authority (CA), also known as a public key infrastructure (PKI) (the public refers to public-key cryptography).
