/git-bash-ssh-key-generate.html. 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. A third-party app I have requires a.pem certificate to be able to open a wss connection. How can I generate a.pem file, keeping in mind that I need that only for testing, therefore I want an easy, not necessarily a really secure way to do so. How to create a PEM file with the help of an automated script: Download NetIQ Cool Tool OpenSSL-Toolkit. Select Create Certificates PEM with key and entire trust chain. Provide the full path to the directory containing the certificate files. Provide the filenames of the following: private key. Public key (server crt). 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. GENERATE CERTIFICATE IN PEM FORMAT. The PEM certificate must to be built with the following structure.
Common OpenSSL Commands with Keys and Certificates

.pem SSL Creation Instructions
SSL .pem files (concatenated certificate container files), are frequently required for certificate installations when multiple certificates are being imported as one file.
This article contains multiple sets of instructions that walk through various .pem file creation scenarios.
Creating a .pem with the Entire SSL Certificate Trust Chain
- Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt), Root (TrustedRoot.crt), and Primary Certificates (your_domain_name.crt).
Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:
- The Primary Certificate - your_domain_name.crt
- The Intermediate Certificate - DigiCertCA.crt
- The Root Certificate - TrustedRoot.crt
Make sure to include the beginning and end tags on each certificate. The result should look like this:
-----BEGIN CERTIFICATE-----
(Your Primary SSL certificate: your_domain_name.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Intermediate certificate: DigiCertCA.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Root certificate: TrustedRoot.crt)
-----END CERTIFICATE-----Save the combined file as your_domain_name.pem. The .pem file is now ready to use.
Creating a .pem with the Server and Intermediate Certificates
- Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).
Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:
- The Primary Certificate - your_domain_name.crt
- The Intermediate Certificate - DigiCertCA.crt
Make sure to include the beginning and end tags on each certificate. We happy few generator key. The result should look like this:
-----BEGIN CERTIFICATE-----
(Your Primary SSL certificate: your_domain_name.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Intermediate certificate: DigiCertCA.crt)
-----END CERTIFICATE-----Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

Creating a .pem with the Private Key and Entire Trust Chain
Openssl Key Pem
- Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).
Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:
- The Private Key - your_domain_name.key
- The Primary Certificate - your_domain_name.crt
- The Intermediate Certificate - DigiCertCA.crt
- The Root Certificate - TrustedRoot.crt
Make sure to include the beginning and end tags on each certificate. The result should look like this:
-----BEGIN RSA PRIVATE KEY-----
(Your Private Key: your_domain_name.key)
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
(Your Primary SSL certificate: your_domain_name.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Intermediate certificate: DigiCertCA.crt)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(Your Root certificate: TrustedRoot.crt)
-----END CERTIFICATE-----Save the combined file as your_domain_name.pem. The .pem file is now ready to use.
