How to install OpenVPN certificate on Android?

How to generate OpenVPN client certificate?

I have an OpenVPN server with my own CA and I need to generate client certificates.

I've looked around a bit but so far found only answers for generating keys, not client certificates. I know how to do this on a different OpenVPN server but would like to know if it's possible to do it on OpenVPN with its own CA (which is also used by other clients).

So I've finally solved this by myself. You can make OpenVPN use its own CA by adding these lines to /etc/openvpn/server.conf (or if you run OpenVPN server as daemon then the location of the file is /etc/openvpn/server.d/ca-bundle.crt

And then start OpenVPN with the -auth-cacert parameter: openvpn --auth-cacert /path/to/your/ca.crt -n /path/to/your/client.conf -c /etc/openvpn/server.conf
This will not change anything in OpenVPN server (ie it will use the same public CA as it normally does) but it will ensure that it is using your own CA when generating client certificates.

How to install certificate for OpenVPN?

I am able to connect to my own VPN, but now I want to share that VPN with other users who may not be familiar with VPN. How do I install a public/shared certificate? I have tried following instructions, but I don't know how to install it. When I use the command, I get this error message:

Code: Error: ERROR: The OpenVPN server's certificate is not trusted by the client. You must add the server's certificate to the directory containing the ca certificate file. (OpenVPN will use that ca to verify the server's certificate). You must add the following lines to your configuration file: I have downloaded it (ca.crt) and the two key files (server.crt and server.key) and then I added them to the /etc/openvpn/easy-rsa/keys directory but still I am not getting this working.

It works! This worked for me. I was never able to connect to openvpn before. I just installed openvpn from the command line as follows. Open the terminal application and change directories to wherever you have downloaded openvpn:
Cd ~/Downloads. Then run the openvpn application: My system is Ubuntu 12.04.3 LTS.

When I run the openvpn application I get the following: Generating a 4096 bit RSA private key. Writing key. ----. No diffie-hellman-group-exchange-extension. A private OpenVPN key for. Jr@jalix.com has been generated.

If you are using OpenVPN on a server or a desktop computer, and if you are generating a 4096 bit key, then there is no need to include the `diffie-hellman-group-exchange-extension` in your generated key. OpenVPN is working fine after I changed my /etc/openvpn/easy-rsa/keys/ca.crt) Now I just need to install my certificate. How do I do that? Re: How to install certificate for OpenVPN?
