Puttygen – Putty Key Generator

One of the keys generation utility PuTTYgen can establish various public-key cryptosystems including Rivest Shamir Adleman (RSA), Digital Signature Algorithm (DSA), Elliptic Curve Digital Signature Algorithm (ECDSA), and Edwards-curve Digital Signature Algorithm (EdDSA) keys.The aforementioned public-key cryptosystems principally consentrate on secure data transmission and digital signatures.Although PuTTYgen collects keys in its native extendable i.e. .ppk files, the keys could be converted to any file format. For Windows, the application interface is PuTTYgen.exe, whereas, for Linux OS the command-line adaptation is accessible using SSH commands.

What is Puttygen?

Puttygen is one tool useful for generating Public and Private SSH keys for servers. You can create the SSH keys with putty gen, as well as it the primary function of it. Putty gen generates the keys in the data format and that is .ppk format. But you can also convert the .ppk format holiday to a format easily. Putty gen is officially designed for Windows, Linux Mac. The Windows version of Putty gen may be the .exe format. You are able to install in your Windows PC and Run it. It possesses a GUI (Graphical User Interface) version for Windows. But Putty gen for Linux or Mac is command based. You have to use some commands to work with Putty gen on Linux or Mac OS. Putty gen is a handy tool if you utilize servers. It could generate different types of SSH keys for the server making it more secure. Should you use Putty, and that is an increasingly popular SSH client, then you can generate the keys for Putty through Puttygen.

Download PuTTYgen

PuTTYgen as being a component of the terminal emulator PuTTY doesn’t have to be downloaded separately, hence, comes with the PuTTY .msi installation package. It is possible to stick to the simple measures to Download PuTTYgen for Windows for your system. That means that you don’t need to download PuTTYgen separately. When you download PuTTY software, you can install and run PuTTYgen easily in no time. Below is the total instruction on how to download and install PuTTY on Windows.

Download PuTTYgen on Windows

To download PuTTYgen the primary requisite should be to discover the copy of PuTTY installation package. For any 64-bit computer, you have to install the 64-bit version of PuTTY, i.e. putty-64bit–installer.msi.Similarly, with the 32-bit os, the respective 32-bit version of PuTTY, i.e. putty–installer.msi ought to be installed. To receive PuTTY, go to PuTTY Installation Download page, whereby the full installation package will be available with setup instructions, installation guide, and download links to all other parts of PuTTY for example putty.exe, pscp.exe, psftp.exe, puttytel.exe, plink.exe, pageant.exe and putty.zip.


To produce a new key pair, select any type of key to generate from the base of the screen (using SSH-2 RSA with 2048 bit key dimension is good for many people; yet another good well-known alternative is ECDSA ). Then click Generate , and begin moving the mouse in the Window. Putty uses mouse movements to accumulate randomness. The exact way you will move your mouse should not be predicted by an external attacker. You should move a button for quite a while, with respect to the size of your respective key. As you move it, saving money progress bar should advance. If the progress bar becomes full, the particular key generation computation takes place. This will likely take from several seconds a number of minutes. When complete, the public key should come in the Window. It’s simple to specify a passphrase to the key. You must save at the least the non-public key by clicking Save private key .It can be far better to also save people key, though it could be later regenerated by loading in which you key.
