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
- A certificate.crt and privateKey.key can be extracted from your Personal Information Exchange file (certificate.pfx) using OpenSSL. Follow this article to create a certificate.crt and privateKey.key files from a certificate.pfx file.
- 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 the public key of the pair and not a private key.
- Jul 17, 2017 How to Generate pem file to ssh the server without Password in Linux. The main file extensions are.pem,.crt. To generate an RSA key pair for version 2 of.
- Openssl x509 -inform DER -outform PEM -in server.crt -out server.crt.pem For server.key, use openssl rsa in place of openssl x509. The server.key is likely your private key, and the.crt file is the returned, signed, x509 certificate. If this is for a Web server and you cannot specify loading a separate private and public key.
- 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.
- Jan 21, 2009 Requirement: Create JKS keystore and truststore out of certificate and private key files given in pem format. Try to open the certificate and key files and it contains ASCII text that starts with -BEGIN CERTIFICATE-, then it is in PEM format. Using keytool in java, when a keystore is created it already has the.
Generate a 2048 bit RSA Key
You can generate a public and private RSA key pair like this:
Openssl Extract Key From Pem
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
Generate Pem From Crt Keyboard
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.
