Sep 26, 2019 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.
T keytype Specifies to the type of a new key to generate. Acceptable values include rsa and dsa. Rsa1 is also supported to generate legacy SSH-1 keys, but they should never be needed any more.-b bits Specifies the number of bits in the key. For DSA keys, 1024 is a decent size. For RSA keys, 2048 or even 4096 bits are recommended. On you computer, click Start, All Programs, PuTTY, and then PuTTYgen. Select SSH-2 RSA in the Parameters area. Enter 1024 in the Number of bits in a generated key field. Click Generate and then move the cursor around the blank area of the Key area to generate the random characters that create a unique key. Mar 28, 2018 Generating RSA-SSH Public Key, OpenSSH & PuTTY Compatible Private Keys using PuTTYgen. In a consideration of security, most of the remote SSH connectivity are now transforming to Password-less RSA Authentication. Basically in this method, authentication is being done on the basis of Private / Public key. In which, Server will have a Public Key and a.
With PuTTYgen you can generate SSH key pairs (public and private key) that are used by PuTTY to connect to your server from a Windows client. The private key will be stored on your local machine, while the public key has to be uploaded in your dashboard. When connecting with PuTTY, your session loaded with your private key will generate a signature which will be authenticated by the server using the matching public key.
Generate Rsa Key Using Puttygen Key
Step 1: Download PuTTYgen
Simply download and save the PuTTYgen executable (.exe) file from this link. Since it’s a standalone application, you will not need to perform any installation steps for it.
Step 2: Generate SSH Key
Open PuTTYgen.
Select these parameters:
Jelastic requires an SSH-2 RSA (recommended) or SSH-2 DSA key
The number of bits can be either 2048 or 4096 (recommended). This defines the strength of the key and its resistance to brute-force attacks.
Click the Generate button.
Move your mouse randomly within the empty area to generate your key until the progress bar fills up.
In the next screen you can see the following:
Your Public Key
You can copy and paste this key directly to your Jelastic dashboard. To see how to add your public key to Jelastic, please see: How to connect to Jelastic using PuTTY
Your Key Fingerprint
In this field you should enter something to help you remember what you will use this key for. For example if you are going to use this key pair to connect to your Jelastic environments, you could enter ‘Jelastic’ here.
Key passphrase
Here you can set a password you can use to encrypt your Private Key. While this is not mandatory, it is strongly recommended to ensure that nobody from your workstation will be able to connect to your server without knowing the passphrase.
If you are using SSH for scripts, you will need to leave the Key passphrase field empty.
Step 3: Save your SSH key
Generate Rsa Key Linux
You can either copy and paste your public key into the Jelastic dashboard, or you can click the ‘Save public key’ button to save the file on your computer. You can open it with a simple text editor, like Notepad.
You should save the private key on your computer as a .ppk (PuTTY Private Key) file.

If you would like to change the comment or passphrase for an existing SSH key, or you would simply like to view the fingerprint or maybe save another copy of the public key, you can always load your SSH key in PuTTYgen.
Open PuTTYgen.
Click Load
Select your SSH Private Key file.
Enter your passphrase if prompted and click OK.
You will see the Public key, fingerprint and related information in the PuTTY Key Generator window.
Important: If you make any changes, don’t forget to save your Private key!
