Once you have created a Certificate Signing Request (CSR), you can create a self-signed certificate from it. A self-signed certificate does not give the security guarantees provided by a certificate signed by a commercial CA. But it will allow you to provide a secure https connection to your web site. Clients will see a warning message stating that your site's identity cannot be verified and thus is not a "trusted site". Clients have the option of accepting the certificate for the session and all subsequent https connections with the site will be secure.

Assuming you had generated your CSR and private key using the method shown above, you can create a self-signed certificate with the following openssl command:

<code>
openssl req -x509 -days 365 -in hostcsr.pem -key hostkey.pem -out hostcert.pem
</code>

Here's and explanation of the command line options:

    * -x509 - output a self-signed certificate rather than a CSR.
    * -days 365 - make the self-signed certificate valid for one year.
    * -in hostcsr.pem - read in the CSR from the file hostcsr.pem.
    * -key hostkey.pem - read in the private key from the file hostkey.pem.
    * -out hostcert.pem - write out the self-signed certificate to the file hostcert.pem.


View The Contents Of A Certificate Signing Request
Once you have created a Certificate Signing Request (CSR), you can look at the contents of the file using a text editor. But you will only see a block of PEM-encoded text such as this:
<file>
    -----BEGIN CERTIFICATE REQUEST-----
    MIIBhzCB8QIBADBIMQswCQYDVQQGEwJVUzERMA8GA1UECBMISWxsaW5vaXMxDzAN

    wpM7Z5VjngNVfWM=
    -----END CERTIFICATE REQUEST-----
</file>
If you want to see the actual entries for this file, you can view the contents as text. Here's is a typical openssl command and the resulting output:

    openssl req -text -noout -in hostcsr.pem

Here's an explanation of the command line options:

    * -text - view the contents of the CSR as plain text.
    * -noout - do not output the PEM-encoded version of the CSR.
    * -in hostcsr.pem - read in the CSR from the file hostcsr.pem.
