Generate tls certificate
Create & sign ssl/tls certificates with openssl
Temporary SSL servers can be set up using self-signed SSL certificates. It’s suitable for test and development servers where security isn’t an issue. To create a self-signed SSL certificate and key, fill out the form below.
To run websites that use the HTTPS protocol, SSL certificates are required. Such a certificate is normally purchased from Verisign, Thawte, or any other SSL certificate provider for specialized web pages. A chain of trust is used in SSL certificates, in which each certificate is signed (trusted) by a higher, more trustworthy certificate. The root certificates, which are held by Verisign and others, are at the top of the chain of trust. Usually, the operating system or web browser may have these certificates.
When you visit a website over HTTPS, your web browser can download the site’s SSL certificate. It will check the certificate’s contents to ensure that it is valid for the domain name you are trying to enter. The chain of trust will then be confirmed. It will check the signature on the certificate. It would equate the certificate to the ones that came with the operating system whether it is a root certificate. If the certificate is not a root certificate, it will continue the chain of trust one step higher.

You may use a self-signed SSL certificate when using SSL for non-production applications or other experiments. Visitors to your site will see a browser alert stating that the certificate can not be trusted, despite the fact that it incorporates maximum encryption.
Simply press return when the openssl req command prompts you for a “challenge password,” leaving the password blank. Certificate Authorities use this password to check the certificate owner’s identity when they want to revoke their certificate. There’s no way to revoke this self-signed certificate via CRL because it’s self-signed (Certificate Revocation List).
How to create a self signed certificate
If you want to use a different tls certificate for clients, fabric, and heartbeat messages, repeat the “Build the server certificates” section above, but change the names of the “server.*” files to something else. Also, make sure to use a special “Common Name.”
The fabric, heartbeat node-to-node authentication, and server authentication to client will all be allowed as a result of the above (client to verify server). If you want the client to authenticate with the server (so that the server can validate the client), you can do stuff like:

Self-signed certificates are not authenticated by any third party unless they have been previously imported into the browsers. You can use a certificate signed by a certificate authority if you need more protection (CA).
A self-signed certificate is simple to create. The openssl req command is all you need. It can be difficult to build one that can be consumed by a wide range of clients, such as browsers and command line utilities.
It’s complicated because browsers have their own set of standards that are more stringent than those set out by the IETF. The browser specifications are documented at the CA/Browser Forums (see references below). The limitations exist in two areas: (2) DNS names and (1) confidence anchors
Modern browsers (such as the warez we’re using in 2014/2015) expect a certificate to be linked to a trust anchor and for DNS names to be shown in specific ways in the certificate. Self-signed server certificates are also being deliberately resisted by browsers.
Importing a self-signed server certificate isn’t always straightforward in some browsers. In reality, some browsers, such as Android’s browser, do not allow it. As a consequence, being your own authority is the full solution.
