Zen Load Balancer is able to manage HTTPS connections (HTTP Profile), so the system administrator must to create their own certificates (self-signed certificates) or to acquire Signed Certificates by a Certificate Authority, in both cases the certificate must to be built in PEM format.

The Secure Certificate must be created without password and the keys and CSR must be generated in the server to be secured.

Save the combined file as yourdomainname.pem. The.pem file is now ready to use. Creating a.pem with the Private Key and Entire Trust Chain. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (yourdomainname.crt). Just as a.crt file is in.pem format, a.key file is also stored in.pem format. Assuming that the cert is the only thing in the.crt file (there may be root certs in there), you can just change the name to.pem. The same goes for a.key file. Which means of course that you can rename the.pem file to.key. Which makes gtrig's answer the.

Positives SSL are ready to go in PEM format but Rapid SSL needs to be converted as each file contains the cert, the intermediate CA and the root CA separated.


The package openssl should be installed in order to generate the keys in the server, in our case will be the Zen Load Balancer instance which should be already installed.

First, generate the key without passphrase.

Then, generate the Certificate Signed Request (.csr) using the generated key (.key) as input.

Once the certificate and intermediate CA files are delivered, ensure to get the issuer root certificate.

All separated files need to be in PEM format: Server Certificate, Intermediate Certificate and Root CA Certificate. If it isn’t, convert the file with the following command:

Finally, we’ve the Private Key, the Certificate issued, the Intermediate Certificate and the Root CA Certificate. All these file contents should be combined to create the PEM file in UNIX format.

Amazon gift card generator 2014 activation key code. How was the problem fixed?Without going too much into detail here: The Program got renamed and instead of it creating a Gift Card it now adds Money directly into the Account via Server Injection.


The PEM certificate must to be built with the following structure.

Generate Pem From Cert And Key Code

To create a correct PEM structure, it’s needed to concatenate the different file contents generated in the step above with the separations:

It’s mandatory to convert the PEM entire file in UNIX format.

It’s available the certificate named zencert.pem for testing purposes in order to be used with HTTPS profile farms.

'OpenSSL' Generating Certificates in DER and PEM

Generate Pem From Cert And Key Pdf

This section provides a tutorial example on how to generate certificates in DER and PEM formats using 'OpenSSL'.

After tested how 'keytool' can be used to export certificates in DER and PEM formats, I decided to try with 'OpenSSL' to see if it can generate certificates in DER and PEM formats or not. What I did was to:

  • Run 'openssl genrsa' to generate a RSA key pair.
  • Run 'openssl req -new -x509' to generate a self-signed certificate and stored it in PEM format.
  • Run 'openssl x509' to convert the certificate from PEM encoding to DER format.

The test session was recorded below:

Now I got one certificate generated by 'OpenSSL' and stored in two files: openssl_crt.der and openssl_crt.pem. How can I verify that they are really using DER and PEM formats? I used 'keytool' to try to view them as described in the next section.
