These protocols are all used to run a remote session on a computer, over a network. PuTTY implements the client end of that session: the end at which the session is displayed, rather than the end at which it runs.
Oct 23, 2013 OS X 10.9 Mavericks - the latest update to Apple's desktop OS - noticeably improves the overall experience on for both new and older Macs.Pros:Free: Mac OS. If you need to burn these to a usb or external hard drive using windows, Then use a program called Transmac. In case of a 32-bit operating system, you will need to install the 32-bit version of PuTTY, i.e. Putty-installer.msi Go to PuTTY Installation Download page, where you will find the download link of PuTTY installation package with the exhaustive details of its installation, setup instruction, verifying release signature, various.
In really simple terms: you run PuTTY on a Windows machine, and tell it to connect to (for example) a Unix machine. PuTTY opens a window. Then, anything you type into that window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the window. So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere else.
What's New:
- Security fix: prevent a nefarious SSH server or network attacker from crashing PuTTY at startup in three different ways by presenting a maliciously constructed public key and signature.
- Security fix: PuTTY no longer retains the private half of users' keys in memory by mistake after authenticating with them.
- Revamped the internal configuration storage system to remove all fixed arbitrary limits on string lengths. In particular, there should now no longer be an unreasonably small limit on the number of port forwardings PuTTY can store.
- Port-forwarded TCP connections which close one direction before the other should now be reliably supported, with EOF propagated independently in the two directions. This also fixes some instances of port-forwarding data corruption (if the corruption consisted of losing data from the very end of the connection) and some instances of PuTTY failing to close when the session is over (because it wrongly thought a forwarding channel was still active when it was not).
- The terminal emulation now supports xterm's bracketed paste mode (allowing aware applications to tell the difference between typed and pasted text, so that e.g. editors need not apply inappropriate auto-indent).
- You can now choose to display bold text by both brightening the foreground colour and changing the font, not just one or the other.
- PuTTYgen will now never generate a 2047-bit key when asked for 2048 (or more generally n−1 bits when asked for n).
- Some updates to default settings: PuTTYgen now generates 2048-bit keys by default (rather than 1024), and PuTTY defaults to UTF-8 encoding and 2000 lines of scrollback (rather than ISO 8859-1 and 200).
- Unix: PSCP and PSFTP now preserve the Unix file permissions, on copies in both directions.
- Unix: dead keys and compose-character sequences are now supported.
- Unix: PuTTY and pterm now permit font fallback (where glyphs not present in your selected font are automatically filled in from other fonts on the system) even if you are using a server-side X11 font rather than a Pango client-side one.
- Bug fixes too numerous to list, mostly resulting from running the code through Coverity Scan which spotted an assortment of memory and resource leaks, logic errors, and crashes in various circumstances.
Legal Warning: Use of PuTTY, PSCP, PSFTP and Plink is illegal in countries where encryption is outlawed. I believe it is legal to use PuTTY, PSCP, PSFTP and Plink in England and Wales and in many other countries, but I am not a lawyer and so if in doubt you should seek legal advice before downloading it. You may find this site useful (it's a survey of cryptography laws in many countries) but I can't vouch for its correctness.
Use of the Telnet-only binary (PuTTYtel) is unrestricted by any cryptography laws.

PuTTYgen is a tool used for generating public and private SSH keys which are its fundamental function. Though it collects keys in its own file format i.e. .ppk files, keys can also be transformed to any other file format quickly. It is available for the various operating system, i.e. Windows, Linux, Mac, etc. PuTTYgen.exe is the graphical tool on Windows OS. While on the other side, Linux OS has the only command-line version.

PuTTYgen is used to generate public or private key pair for creating SSH keys. Below is the complete guidance about how to generate RSA key in Windows operating system:
- Once you install the PuTTY on your machine, you can easily run PuTTYgen. For the same, go to Windows -> Start Menu -> All Programs -> PuTTY -> PuTTYgen.
- You will see the PuTTY key generator dialog box on your screen
- You will find a “Generate” button in that dialog. Clicking on it will lead to generating the keys for you.
- Now you will need to add a unique key passphrase in the Key passphrase and Confirm passphrase field.
- Click on the “Save Public Key” and “Save Private Key” buttons to save your public and private keys.
- You will see the text starting with ssh-RSA in the Public key for pasting into OpenSSH authorized_keys file field which is located at the top of the window. Copy that entire text to your clipboard by pressing ctrl+c as you will require the key to paste on your clipboard in the public key tool of control panel or directly on the cloud server.
Various Ways to Use RSA Key Pair
RSA key pair generated through PuTTYgen is used in two various ways defined as below:
- To assign while creating a new cloud server
You can choose the public key from the given list of keys at the time of creating cloud server. If you don’t find your key in that list, then first add and then assign it. - Assign to an existing cloud server
At the time of connecting to the cloud server, first of all, you need to tell PuTTY to use it for utilizing your newly created RSA key pair.
The installation of PuTTYgen is very simple as it is installed as a part of normal PuTTY .msi package installation. You can follow the simple steps to download PuTTYgen software for your system. That is the reason why you don’t need to download PuTTYgen separately. Once you download PuTTY software, you will be able to install and run PuTTYgen easily in no time. Below is the complete instruction about how to download and install PuTTY on Windows.

Generate Key Pair for Authentication in Linux
Use the below command to create the key pair for authentication in Linux.
PuTTYgen -t RSA -b 2048 -C “user@host” -o keyfile.ppk
Various Command Line Options of PuTTY in Linux
Below is the list of important command line options for PuTTY in Linux operating system.
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 – This command specifies the type of the 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 – This command suppresses the message about progress at the time of key generation.
- -C new-comment – This command is used to specify the comment to describe the key. It can be used for new and/or existing key. Key operation is not affected by comment. However, it is used to recognize the key owner, it’s not reliable completely as any value can be applied to it.
- –P – This command is used to update the passphrase of a key. Passphrase helps to encrypt the private key. As passphrase can’t be add or update on command line, it prompts a new passphrase tool to alter it.
- –old-passphrase-file – The old password of the key remains in this file. This is used when the key is protected by a passphrase.
- –new-passphrase file – This file entails the new passphrase of the key. This command comes in the action either at the time of generating 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.
Thus, above are the prominent commands of PuTTYgen in Linux operating system. There are many other commands also available to perform a various task from the command prompt in Linux at flank speed.
