Self-signed ssl certificates can be used to set up temporary ssl servers. You can use it for test and development servers where security is not a big concern. Use the form below to generate a self-signed ssl certificate and key.
About SSL Certificates
SSL certificates are required in order to run web sites using the HTTPS protocol. For professional web sites, you usually buy such a certificate from Verisign, Thawte or any other ssl certificate vendor. SSL certificates use a chain of trust, where each certificate is signed (trusted) by a higher, more credible certificate. At the top of the chain of trust are the root certificates, owned by Verisign and others. These certificates are typically shipped with your operating system or web browser.

Generate self-signed SSL certificate in one line. As a web developer or website owner, you may sometimes need to generate and test your web application using self-signed SSL certificates before buying commercial SSL certificates. Generating self-signed certificates is an easy process. In fact, it's a one-step process.
When you visit a web site over HTTPS, your web browser will receive the ssl certificate for the web site. It will examine the contents of the certificate to see that is indeed valid for the domain name you are trying to visit. After that, it will verify the chain of trust. It will look at who has signed the certificate. If that certificate is a root-certificate, it will compare it against the ones shipped with the operating system. If it is a non-root certificate, it will follow the chain of trust up one more level.
Self-signed certificates
When using a self-signed certificate, there is no chain of trust. The certificate has signed itself. The web browser will then issue a warning, telling you that the web site certificate cannot be verified. Therefore, you should not use self-signed certificates for professional use, as your visitors will not trust your web site to be safe.
- Jul 08, 2009 Get a Valid Trial SSL Certificate (Optional) Instead of signing it youself, you can also generate a valid trial SSL certificate from thawte. I.e Before spending the money on purchasing a certificate, you can also get a valid fully functional 21 day trial SSL certificates from Thawte. Once this valid certificate works.
- Generating a private key and CSR. To generate a private key and CSR from the command line, follow these steps: Log in to your account using SSH. At the command prompt, type the following command: openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr.
- You can do this with these steps: 1. Type the following command in an open terminal window on your computer to display the list of curves supported by your version of OpenSSL. Once you have selected a curve, then you can use the following command to create the private key file.

What is a self-signed SSL certificate? A self-signed certificate is a certificate that is not signed by a trusted authority.
Nevertheless, the self-signed certificate provides the same level of encryption as a $100500 certificate signed by a trusted authority.
In this article i will show how to create a self-signed certificate that can be used for non-production or internal applications.
