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
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. An Online RSA Public and Private Key Generator. Sep 6 th, 2013. I was recently in a meeting where a person needed to generate a private and public key for RSA encryption, but they were using a PC (Windows). This is something that is easily done via a terminal using ssh-keygen on Mac and Linux.
Generate a 2048 bit RSA Key
How can I find the private key for my SSL certificate. If you just got an issued SSL certificate and are having a hard time finding the corresponding private key, this article can help you to find that one and only key for your certificate. How to: Create a public-private key pair.; 2 minutes to read; In this article. To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). To install the public key, Log into the server, edit the authorizedkeys file with your favorite editor, and cut-and-paste the public key output by the above command to the authorizedkeys file. Save the file. Configure PuTTY to use your private key file (here keyfile.ppk). Then test if login works. See configuring public key authentication for.
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.pem
to verify that it starts with a-----BEGIN RSA PRIVATE KEY-----
less public.pem
to 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.

On Windows, you can create SSH keys in many ways. This document explains how to use two SSH applications, PuTTY and Git Bash.
Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.
PuTTY
PuTTY is an SSH client for Windows. You can use PuTTY to generate SSH keys. PuTTY is a free open-source terminal emulator that functions much like the Terminal application in macOS in a Windows environment. This section shows you how to manually generate and upload an SSH key when working with PuTTY in the Windows environment.
About PuTTY
PuTTY is an SSH client for Windows that you will use to generate your SSH keys. You can download PuTTY from www.chiark.greenend.org.uk.
When you install the PuTTY client, you also install the PuTTYgen utility. PuTTYgen is what you will use to generate your SSH key for a Windows VM.
This page gives you basic information about using PuTTY and PuTTYgen to log in to your provisioned machine. For more information on PuTTY, see the PuTTY documentation |
---|
Generating an SSH key
To generate an SSH key with PuTTYgen, follow these steps:
- Open the PuTTYgen program.
- For Type of key to generate, select SSH-2 RSA.
- Click the Generate button.
- Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair.
- Type a passphrase in the Key passphrase field. Type the same passphrase in the Confirm passphrase field. You can use a key without a passphrase, but this is not recommended.
- Click the Save private key button to save the private key. You must save the private key. You will need it to connect to your machine.
- Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
- Right-click again in the same text field and choose Copy.
Importing your SSH key
Now you must import the copied SSH key to the portal.
- After you copy the SSH key to the clipboard, return to your account page.
- Choose to Import Public Key and paste your SSH key into the Public Key field.
- In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
- Add the key. It will now appear in your table of keys under SSH.
PuTTY and OpenSSH use different formats of public SSH keys. If the text you pasted in the SSH Key starts with —— BEGIN SSH2 PUBLIC KEY
, it is in the wrong format. Be sure to follow the instructions carefully. Your key should start with ssh-rsa AAAA…
.
Once you upload your SSH key to the portal, you can connect to your virtual machine from Windows through a PuTTY session.
Git Bash
The Git installation package comes with SSH. Using Git Bash, which is the Git command line tool, you can generate SSH key pairs. Git Bash has an SSH client that enables you to connect to and interact with Triton containers on Windows.
To install Git:
- (Download and initiate the Git installer](https://git-scm.com/download/win).
- When prompted, accept the default components by clicking Next.
- Choose the default text editor. If you have Notepad++ installed, select Notepad++ and click Next.
- Select to Use Git from the Windows Command Prompt and click Next.
- Select to Use OpenSSL library and click Next.
- Select to Checkout Windows-style, commit Unix-style line endings and click Next.
- Select to Use MinTTY (The default terminal of mYSYS2) and click Next.
- Accept the default extra option configuration by clicking Install.
When the installation completes, you may need to restart Windows.
Launching GitBash
To open Git Bash, we recommend launching the application from the Windows command prompt:
- In Windows, press Start+R to launch the Run dialog.
- Type
C:Program FilesGitbinbash.exe
and press Enter.
Generating SSH keys
First, create the SSH directory and then generate the SSH key pair.
One assumption is that the Windows profile you are using is set up with administrative privileges. Given this, you will be creating the SSH directory at the root of your profile, for example:
- At the Git Bash command line, change into your root directory and type.
Change into the .ssh directory
C:Usersjoetest.ssh

- To create the keys, type:
- When prompted for a password, type apassword to complete the process. When finished, the output looks similar to:
Uploading an SSH key
To upload the public SSH key to your Triton account:
- Open Triton Service portal, select Account to open the Account Summary page.
- From the SSH section, select Import Public Key.
- Enter a Key Name. Although naming a key is optional, labels are a best practice for managing multiple SSH keys.
- Add your public SSH key.
When Triton finishes the adding or uploading process, the public SSH key appears in the list of SSH keys.
