While moving from the Windows to Mac OS is a nice experience, you would miss the PuTTY system on Mac if you have been used to using it on Windows. Whether you are a system admin or a website owner, it's a common application that most of us have used at least once in their lifetime.
Download and install Quartz. Download and install MacPorts. Sudo port -v selfupdate. Type this command sudo port install putty. Type Putty into the terminal. Create a shortcut: cp/opt/local/bin/putty /Desktop/PuTTY. You now have installed the mac port of PuTTY on your Mac OS X! I have no experiences with this App: ZOC - I only did a quick Google on 'OS X telnet GUI' and got a link to this product as the first hit - but it seems to do the same as PuTTY. There is a 30 days trial available. ZOC is a professional SSH/telnet client and terminal emulator. With its impressive list of emulations it lets you easily connect to hosts and mainframes, using communication methods. PuTTY grew out of a telnet client. It still supports the telnet protocol. However, very few devices use telnet these days. Its use is not recommended for security reasons. Telnet sends all user names and passwords in the clear. It is very easy to listen to network traffic and steal user names and passwords from telnet traffic. By mid-1990s, such password sniffing attacks had become the largest security problem on the Internet. PuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator. It is written and maintained primarily by Simon Tatham. The latest version is 0.74.
PuTTY is a free terminal emulator that helps you transfer files over the same network, by logging from another computer. It can also be accessed over the internet. You can secure the file transfer facility by adding SCP and SFTP. Security is the biggest concern with PuTTY, but you can add verification and encryption by using it in combination with SSH. This helps shield the connections over the internet.
While many dedicated users still prefer using PuTTY, it can be tough for those who have recently shifted to Mac. So, here's a quick list of some of the best PuTTY alternative for Mac OS that we think can make your life easy.
Terminal
It's the default terminal emulator that comes embedded in the Mac OS. It's a wonderful tool that helps break down into the command line. So, when you are logged into multiple servers, you will easily be able to identify the special background colors and the window titles mentioned in profiles. You can either use the built-in profiles in the Terminal or can even make your own custom profiles.
Just Press Command and Spacebar and search Terminal in Spotlight. Now, just write ssh [email protected] to connect to the server.
Moreover, it allows you to add bookmarks while working which can be then used to quickly maneuver through the extended Terminal window. The best part is, the inspector helps you to view and control the ongoing processes, and even lets you adjust the window titles and background colors.

You can get a terminal that's always available by setting the hotkey to open a dedicated pane. Moreover, it features powerful search functionality, while the interface stays distant. As soon as you input your search term, the matches are instantly highlighted.
Autocomplete is another feature where as you type the first letter of any word that you might have used earlier, followed with 'Cmd' and the word comes up at the top of the list.

- 1.2 Download PuTTYgen for Mac
- 1.3 Download PuTTYgen for Ubuntu/Linux
- 1.3.3 Types of Keys Supported on PuTTYgen
Puttygen aka Putty Key Generator
The key generation utility – PuTTYgen can create 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 focus on secure data transmission and digital signatures.
Although PuTTYgen collects keys in its native file format i.e. .ppk files, the keys can easily be converted to any file format. For Windows, the software interface is PuTTYgen.exe, whereas, for Linux OS the command-line adaptation is available using SSH commands.
How to use PuTTYgen?
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 the 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 a 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.

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:
Putty For Telnet On Mac Os
PuTTYgen [-t keytype [-b bits] [-q] | keyfile]
[-C new-comment] [-P]
[-O output-type | -p | -l | -L]
[-o output-file]
Putty For Telnet On Mac Catalina
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.
