Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms.
Payday 2 license key generator. UNIX and UNIX-like platforms (including Solaris and Linux) include the ssh-keygen utility to generate SSH key pairs.
filename
your choice of file name for the private key:The ssh-keygen utility prompts you for a passphrase for the private key.
Note:
While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.
The ssh-keygen utility prompts you to enter the passphrase again.

. It also displays information about the key fingerprint and randomart image.The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform.
O Causes ssh-keygen to save private keys using the new OpenSSH format rather than the more compatible PEM format. The new format has increased resistance to brute-force password cracking but is not supported by versions of OpenSSH prior to 6.5. Ed25519 keys always use the new private key. Jul 28, 2018 Step 1.

While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.
.ppk
(PuTTY private key).Note:
The.ppk
file extension indicates that the private key is in PuTTY's proprietary format. You must use a key of this format when using PuTTY as your SSH client. It cannot be used with other SSH client tools. Refer to the PuTTY documentation to convert a private key in this format to a different format. Make sure you select all the characters, not just the ones you can see in the narrow window.

PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a .ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion. This tool, available for both Windows and Unix operating system, can convert keys.
Windows - install PuTTYgen
Most Windows operating systems have PuTTY installed. If your system doesn't, download and install PuTTYgen.
Windows - convert a .pem file to a .ppk file
Start PuTTYgen, and then convert the .pem file to a .ppk file. For detailed steps, see Convert Your Private Key Using PuTTYgen.

To install PuTTY, run one of the following commands:
RPM-based
Dpkg-based
