You can export the certificates and private key from a PKCS#12 file and save them in PEM format to a new file by specifying an output filename: openssl pkcs12 -in INFILE.p12 -out OUTFILE.crt -nodes Again, you will be prompted for the PKCS#12 file’s password.

To generate the Private key from the .jks file from linux/unix server.

We can use keytool and openssl utility to generate the private key from a .crt/.jks file.

Command to use:

Go to the location where your certificate file is located.

Using Keytool command generate keystore file

keytool -v -importkeystore -srckeystore keystore.jks -srcalias keyalias -destkeystore keystore.p12 -deststoretype PKCS12

Using Openssl generate the .pem file which contains the private key

openssl pkcs12 -in keystore.p12 -out keystore.pem

keystore.jks – This file is your certificate file. It will be either in .crt or .jks format.

The keystore.pem contains your private key.

While running the command if it prompts for password you should give it as per the password added while creating a cert file.

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.

In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with mod_ssl.

Key, CSR and CRT File Naming Convention

I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. This makes it easier to identify and maintain.

Instead of server.key, I use www.thegeekstuff.com.key
Instead of server.csr, I use www.thegeekstuff.com.csr
Instead of server.crt, I use www.thegeekstuff.com.crt

1. Generate Private Key on the Server Running Apache + mod_ssl

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.

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

For testing purpose, you can generate a self-signed SSL certificate that is valid for 1 year using openssl command as shown below.

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.
