    ## Generation of a Self Signed Certificate
    Generation of a self-signed SSL certificate involves a simple 3-step procedure:

    __STEP 1__: Create the server private key
    ```sh
    openssl genrsa -out cert.key 2048
    ```
    __STEP 2__: Create the certificate signing request (CSR)
    ```sh
    openssl req -new -key cert.key -out cert.csr
    ```
    __STEP 3__: Sign the certificate using the private key and CSR
    ```sh
    openssl x509 -req -days 3650 -in cert.csr -signkey cert.key -out cert.crt
    ```
    Congratulations! You now have a self-signed SSL certificate valid for 10 years.
