If you want to convert your website from HTTP to HTTPS, you need to get a SSL certificate from a valid organization like Verisign or Thawte. You can also generate self signed SSL certificate for testing purpose.

First, generate a private key on the Linux server that runs Apache webserver using openssl command as shown below.

The generated private key looks like the following.

History of asymmetric cryptographyWhitfield Diffie and Martin Hellman, researchers at Stanford University, first publicly proposed asymmetric encryption in their 1977 paper, 'New Directions in Cryptography.' How asymmetric public private key pairs are generated in california. As a result, ECC key sizes can be significantly smaller than those required by RSA yet deliver equivalent security with lower computing power and battery resource usage making it more suitable for mobile applications than RSA.

2. Generate a Certificate Signing Request (CSR)

Using the key generate above, you should generate a certificate request file (csr) using openssl as shown below.

3. Generate a Self-Signed SSL Certificate

You can use this method to generate Apache SSL Key, CSR and CRT file in most of the Linux, Unix systems including Ubuntu, Debian, CentOS, Fedora and Red Hat.

4. 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, you can either decide to purchase it from Thawte or any other SSL signing organization.

This step is optional and not really required. For testing purpose, you can always use the self-signed certificate that was generated from the above step.

Go to Thwate trial certificate request page and do the following:

Select “SSL Web Server Certificate (All servers)” under the “select your trial certificate”.
Do not check the PKCS #7 check-box under the “configure certificate”
Copy/Paste the *.csr file that you generate above in the textbox under “certificate signing request (CSR)”
Click on next at the bottom, which will give you a 21-day free trial certificate.

Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
