Generate Cert Pem Key Pem
Hey, complete beginner here just want to confirm I am doing the right thing. I wanted to generate a. Key.pem certificate.pem for my https server using node.js. Is this command correct? Openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem. $ openssl x509 -in hostname.crt -inform DER -out hostname.crt.pem -outform PEM $ openssl rsa -in hostname.key -out hostname.key.pem -outform PEM Then to create the.pem I usually use just concat the two together with the PEM formatted certificate first and the key second. May 29, 2015 Connect can be configured with Stunnel to support HTTPS and RTMPS. Stunnel requires you to provide a private key and a public cert file in.pem format. You probably run Stunnel as a service (you should) so you also need to save the private key without a passphrase. If you have a.pfx file with. The tutorial I'm following to create and sign certificates bounces between creating.key and.key.pem files with the -keyout option. For example: master-ca.key.pem and openvpn-ica.key and again vpn-server.key.pem. Does it matter and is there a standard?

How to Create a .pem file with the Entire SSL Certificate Trust Chain
– Login to your SSL Certificate Management Console and download your Intermediate (YourCA.crt), Root (TrustedRoot.crt), and Primary Certificates (your_domain_name.crt).
– Open a text editor 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 – YourCA.crt
The Root Certificate – TrustedRoot.crt
Make sure to include the beginning and end tags on each certificate. The result should look like this: Microsoft project professional 2010 activation key generator.
—–BEGIN CERTIFICATE—–
(Your Primary SSL certificate: your_domain_name.crt)
—–END CERTIFICATE—–
—–BEGIN CERTIFICATE—–
(Your Intermediate certificate: YourCA.crt)
Create Pem Key
—–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.
How to Create a .pem file with the Server and Intermediate Certificates
– Login into your SSL Certificate Management Console and download your Intermediate (YourCA.crt) and Primary Certificates (your_domain_name.crt).
– Again Open a text editor 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 – YourCA.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: YourCA.crt)
—–END CERTIFICATE—–
Save the combined file as your_domain_name.pem. The .pem file is now ready to use.
How to Create a .pem file with the Private Key and Entire Trust Chain
Login into your SSL Certificate Management Console and download your Intermediate (YourCA.crt) and Primary Certificates (your_domain_name.crt).
Open a text editor 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 – YourCA.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: YourCA.crt)
—–END CERTIFICATE—–
—–BEGIN CERTIFICATE—–
(Your Root certificate: TrustedRoot.crt)

Save the combined file as your_domain_name.pem. The .pem file is now ready to use.
While Encrypting a File with a Password from the Command Line using OpenSSLis very useful in its own right, the real power of the OpenSSL library is itsability to support the use of public key cryptograph for encrypting orvalidating data in an unattended manner (where the password is not required toencrypt) is done with public keys.
The Commands to Run
Generate a 2048 bit RSA Key
You can generate a public and private RSA key pair like this:
openssl genrsa -des3 -out private.pem 2048
That generates a 2048-bit RSA key pair, encrypts them with a password you provideand writes them to a file. You need to next extract the public key file. You willuse this, for instance, on your web server to encrypt content so that it canonly be read with the private key.
Export the RSA Public Key to a File
This is a command that is
openssl rsa -in private.pem -outform PEM -pubout -out public.pem
The -pubout flag is really important. Be sure to include it.
Next open the public.pem and ensure that it starts with-----BEGIN PUBLIC KEY-----. This is how you know that this file is thepublic key of the pair and not a private key.
To check the file from the command line you can use the less command, like this:
less public.pem
Do Not Run This, it Exports the Private Key
A previous version of the post gave this example in error.
openssl rsa -in private.pem -out private_unencrypted.pem -outform PEM
The error is that the -pubout was dropped from the end of the command.That changes the meaning of the command from that of exporting the public keyto exporting the private key outside of its encrypted wrapper. Inspecting theoutput file, in this case private_unencrypted.pem clearly shows that the keyis a RSA private key as it starts with -----BEGIN RSA PRIVATE KEY-----.
Visually Inspect Your Key Files
It is important to visually inspect you private and public key files to makesure that they are what you expect. OpenSSL will clearly explain the nature ofthe key block with a -----BEGIN RSA PRIVATE KEY----- or -----BEGIN PUBLIC KEY-----.
You can use less to inspect each of your two files in turn:
less private.pemto verify that it starts with a-----BEGIN RSA PRIVATE KEY-----less public.pemto verify that it starts with a-----BEGIN PUBLIC KEY-----
The next section shows a full example of what each key file should look like.
The Generated Key Files
The generated files are base64-encoded encryption keys in plain text format.If you select a password for your private key, its file will be encrypted withyour password. Be sure to remember this password or the key pair becomes useless.
The private.pem file looks something like this:
The public key, public.pem, file looks like:
Protecting Your Keys
Depending on the nature of the information you will protect, it’s important tokeep the private key backed up and secret. The public key can be distributedanywhere or embedded in your web application scripts, such as in your PHP,Ruby, or other scripts. Again, backup your keys!
Remember, if the key goes away the data encrypted to it is gone. Keeping aprinted copy of the key material in a sealed envelope in a bank safety depositbox is a good way to protect important keys against loss due to fire or harddrive failure.
Oh, and one last thing.
If you, dear reader, were planning any funny business with the private key that I have just published here. Know that they were made especially for this series of blog posts. I do not use them for anything else.
