Generate Fingerprint Of Rsa Public Key Openssl
Posted By admin On 10.04.20Jan 01, 2012 We intend to generate a pair of rsa keys for ssh to work on a cisco router, but we need to generate the rsa key fingerprint from the der format showed in the –sh crypto key rsa command output in the hex format, we use your code to generate the fingerprint but it doesent match with the fingerprint showed in the ssh client’s propt (we used putty) this is the problem. This module allows one to (re)generate OpenSSL private keys. One can generate RSA, DSA, ECC or EdDSA private keys.; Keys are generated in PEM format. Please note that the module regenerates private keys if they don’t match the module’s options.

The comparatively short symmetric key is than encrypted with RSA. Both the RSA-encrypted symmetric key and the symmetrically-encypted message are transmitted to Alice. This service allows you to create an RSA key pair consisting of an RSA public key and an RSA private key. The RSA public key is used to encrypt the plaintext into a ciphertext. You’re looking for a pair of files named something like iddsa or idrsa and a matching file with a.pub extension. The.pub file is your public key, and the other file is the corresponding private key. If you don’t have these files (or you don’t even have a.ssh directory), you can create them by running a program called ssh-keygen, which is provided with the SSH package on Linux/macOS. $ ssh-keygen -t rsa -b 4096 -C 'youremail@example.com' This creates a new ssh key, using the provided email as a label. Generating public/private rsa key pair. When you're prompted to 'Enter a file in which to save the key,' press Enter. This accepts the default file location. This module allows one to (re)generate OpenSSL public keys from their private keys. Keys are generated in PEM or OpenSSH format. The module can use the cryptography Python library, or the pyOpenSSL Python library. By default, it tries to detect which one is available. The fingerprint of the public key. Fingerprint will be generated for each. In public-key cryptography, a public key fingerprint is a short sequence of bytes used to identify a longer public key.Fingerprints are created by applying a cryptographic hash function to a public key. Since fingerprints are shorter than the keys they refer to, they can be used to simplify certain key.
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

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.

You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.
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.
About Terminal
Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.
To open the macOS Terminal, follow these steps:
- In Finder, choose Utilities from the Applications folder.
- Find Terminal in the Utilities listw.
- Open Terminal.
The Terminal window opens with the commandline prompt displaying the name of your machine and your username.
Generating an SSH key
Generate Fingerprint Of Rsa Public Key Openssl Free
An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use ssh-keygen
to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.
To generate SSH keys in macOS, follow these steps:
Enter the following command in the Terminal window.
This starts the key generation process. When you execute this command, the
ssh-keygen
utility prompts you to indicate where to store the key.Press the ENTER key to accept the default location. The
ssh-keygen
utility prompts you for a passphrase.- Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.
You will need to enter the passphrase a second time to continue.
After you confirm the passphrase, the system generates the key pair.
Your private key is saved to the id_rsa
file in the .ssh
directory and is used to verify the public key you use belongs to the same Triton Compute Service account.
Rsa Public Key Encryption
Never share your private key with anyone! |
---|
Your public key is saved to the id_rsa.pub
;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this:
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.
Troubleshooting
You may see a password prompt like this:
This is because:
- You did not enter the correct passphrase.
- The private key on your Macintosh (
id_rsa
) does not match the public key stored with your Triton Compute Service account. - The public key was not entered correctly in your Triton account.
Use Openssl To Generate Key Pair
What are my next steps?
Openssl Rsa Public Key
Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines.
Generate Key With Openssl
In order to use the Terminal to create instances, set up triton
and CloudAPI as well as the triton-docker
commandline tool.
