How to generate OpenVPN client certificate?
I found the following article, which explains . But it seems to me that it is very outdated. The problem is that now you should use this command:
sudo keytool -genkeypair -v -keystore .android/truststore.jks -alias aliasname -validity 3650 -keysize 2048
The second problem, there is no more ~/.android directory. So you should use this command instead:
.jks As I understand that the main reason of migration from the first to the second version is security reasons. Here is an example of the new output: keytool error: java.lang.RuntimeException: Generating a 2048-bit RSA private key requires a 1024-bit key size
And here is another question: Is keytool generated a public/private RSA keypair automatically? Or do I have to do it? Is it secure to keep a private key unprotected in. plaintext? Is it safe to encrypt a private key with a. AES/CTR? Does it mean that the keystore has two different types of RSA keys - private and public? How does the private key encryption work? 1) No, it doesn't need to be a public/private keypair and there is no ~/.android/ for example.
2) Yes, but it is not recommended. It may lead to a weak private key which can be brute forced or otherwise attacked. If you want to keep your private key as it is you should store it either in /home/youruser/.android/keystore or somewhere more robust.
3) Yes. 4) It means that your private key is either encrypted or can be stored only in memory or some other way (ie not written on your SD card). The public part is stored in .bks and will be exported as BKScertscertificate.bks at some point. Also if you use Keystore Explorer for Windows you will be able to see all your stored keys and certificates.
5) I don't understand what do you mean by that.
Does OpenVPN require client certificate?
I'm setting up a remote VPN server for my company and am struggling with getting client certificates to work. I can get the server to work without a certificate, and can also get the client to connect with a certificate using the "--tls-auth" option, but it never asks for the client certificate. I've done some reading around this and it seems that OpenVPN should not be asking for a client certificate as it is supposed to be a server side certificate (ie not something the client will send to the server).
Is this correct? If not, then why not, and what's the best way to configure this sort of thing? Client certificates are used when the client is authenticating itself to the server; OpenVPN doesn't care about your client, but just makes sure you're the person you say you are.
