Chapter 2. Creating RSA public-private key pair

The RSA public-private key pair is required to install the Red Hat OpenShift Data Foundation Managed Service provider and consumer add-ons.

Note

The following procedure uses OpenSSL to create the public-private key pair. You can use any other method to create the RSA public-private key pair.

Prerequisites

  • Ensure you have OpenSSL installed on your machine.

Procedure

  1. To create the private key, run the following command using the command-line interface: 

    $ openssl genrsa -out key.pem 4096
    Copy to Clipboard Toggle word wrap

    Example output

    Generating RSA private key, 4096 bit long modulus(2 primes)

.......................++++
    Copy to Clipboard Toggle word wrap

  2. To create the public key, run the following command using the command-line interface: 

    $ openssl rsa -in key.pem -out pubkey.pem -outform PEM -pubout
    Copy to Clipboard Toggle word wrap

    Example output

Verification steps

  1. To check if the private key is generated, run the following command: 

    $ ls
    Copy to Clipboard Toggle word wrap

    Example output

    key.pem
    Copy to Clipboard Toggle word wrap

  2. To check if the public key is generated, run the following command: 

    $ ls
    Copy to Clipboard Toggle word wrap

    Example output

    pubkey.pem
    Copy to Clipboard Toggle word wrap
