puttygen -t rsa -b 2048 -C 'user@host' -o keyfile.ppk
Various Command Line Options of PuTTY in Linux
Below are few important command line options in the Linux operating system for PuTTY:
PuTTYgen [-t keytype [-b bits] [-q] | keyfile]
[-C new-comment] [-P]
[-O output-type | -p | -l | -L]
[-o output-file]
[-C new-comment] [-P]
[-O output-type | -p | -l | -L]
[-o output-file]
Options:
- Keyfile – It is the name of the existing key file to read at the time of changing the current key.
- –t keytype – The command specifies the type of key to creating. Its acceptable values are RSA and dsa.rsa1.
- -b bits – This command specifies a total number of bit in a particular key. 1024 is the perfect size for DSA key, while 2048 or 4096 are the perfect size for RSA keys.
- –q – The command suppresses the message about progress at the time of key generation.
- -C new-comment – The command will specify the comment to describe the key. It can be used for the new and/or existing key. Key operation is not affected by a comment. However, it is used to recognize the key owner, it’s not reliable completely as any value can be applied to it.
- –P – Using the command will update the passphrase of a key. Passphrase helps to encrypt the private key. As passphrase can’t add or update on a command line, it prompts a new passphrase tool to alter it.
- –old-passphrase-file – The old password of the key remains in this file. The command is used when the key is protected by a passphrase.
- –new-passphrase file – This command prompts the new passphrase of the key. It comes in the action either at the time of generating a new key or while applying –P command to change the passphrase.
- -O output-type – This command defines what to give in output. By default, the private key is the output.

This tutorial will show you how to generate and secure SSH keys on macOS Sierra (10.12) and macOS High Sierra (10.13). Core keygen windows 7 key generator v1 14. SSH keys allow you to log into your server without a password. They increase convenience as well as security by being significantly more resistant to brute-force attacks.
SSH (Secure Shell) is a protocol most often used for remote management and for file transfer often denoted as sFTP (Secure File Transfer Protocol). When accessing a remote server such as a Vultr VPS, it is recommended to use SSH with PKE (Public Key Exchange) which uses a key-pair where the public key is provided to the server and the private key in stored on your machine.
SSH Keys can be automatically added to servers during the installation process by adding your public keys in the Vultr control panel. You can manage your SSH keys on this page. It is important to remember that these are your public keys only (usually denoted with
.pub
), you should never expose your private keys.
Key types
Create New Ssh Key
There are several different key types that can be selected. Use the
-t
argument upon generation, such as ssh-keygen -t ed25519
. The ED25519 key type, which uses an elliptic-curve signature, is more secure and more performant than DSA or ECDSA. Most modern SSH software (such as OpenSSH since version 6.5) supports the ED25519 key type, but you may still find software that is incompatible, thus the default key type is still RSA.
The default key type is 2048-bit RSA which offers good security and compatibility. For higher security, you can choose a larger key size using the
-b
argument on generation, such as ssh-keygen -b 4096
to create a 4096-bit RSA key pair.
Key generation
To generate an SSH key, you will need to open
Terminal.app
found in 'Applications > Utilities > Terminal'. How to save mac os mojave download.
To create a 4096-bit RSA key pair, enter:
Then you will see:
Pressing Enter/Return will save your new key pair to this default location, which is recommended. You will then have the option to create a passphrase, which will encrypt the key so that it cannot be used without authorization. Using a passphrase is also recommended.
Generate Rsa Key On Mac
At this point, your keypair has been created and stored in
~/.ssh/id_rsa
. To make the key available to the system and store the passphrase in the system keychain, we will need to complete several additional steps. Note that this is only needed if you would rather not be prompted for the key passphrase each time it is used.
Add new keypair to SSH agent
Enter
ssh-add -K ~/.ssh/id_rsa
. You will then be prompted for the passphrase and you will see the following:
If you would like to use this SSH key to log into a server that has already been created, you can use the
ssh-copy-id
tool to store the public key on the server you would like to access.
Add new key to remote server
Generate Ssh Key On Mac
Using
ssh-copy-id
:
The console will request your login password since the remote server is not yet aware of your key. You will see the following:
