Creating an OpenSSL certificate: How to do it

OpenSSL allows connections on the Internet to be secured using a protocol. However, creating a certificate is relatively complicated You first need the OpenSSL toolkit to generate a key file. You then receive a signed SSL certificate with the certificate signing request.

What do you need to do to get an OpenSSL certificate?

OpenSSL is the open source implementation of the Secure Sockets Layer (SSL) encryption protocols and its successor Transport Layer Security (TLS). The software library lets you create private RSA keys, certificate signing requests, and checksums. You can also manage your certificates and perform encryption and decryption operations. Note that a certificate you create yourself is not signed by an open certificate authority and therefore causes a warning in the browser.

1. With Open SSL, you can perform all the steps at once with the following command. "openssl -req -new -days 999 -newkey rsa:4096bits -sha512 -nodes -out server.crt -keyout server.key".
2. First, set the OpenSSL configuration environment variables. To do this, open the command prompt as administrator and enter the command "set OPENSSL_CONF=c:\Program Files\Tableau\Tableau Server\<version>\apache\conf\openssl.cnf".
3. Then generate a key file. Be sure to change to the Apache "bin" directory for Tableau Server before entering the necessary commands.
4. Now create a certificate signing request in the form of a CSR file. Then enter the necessary information when prompted.
5. Now send this to a certificate authority to obtain your SSL certificate. You can find a suitable certificate authority with a Google search.
6. Finally, you can use the key and certificate to configure a Tableau Server to use SSL.
