A must-have utility tool for developers

PuTTY is a free and open-source data transfer, terminal emulator, and serial console for Windows. It supports various network protocols to establish a secure connection for transferring sensitive information. Created by Simon Tatham, this is now maintained by developers from around the world. It offers a command-line interface that you can customize according to your requirements. The cross-platform software is available with source code and can also be downloaded on Mac devices.

What is PuTTY?

PuTTY is a free and open-source software for Windows devices that gives users the option to transfer data securely and safely. The client uses different file transfer protocols such as SCP, SSH, SFTP, and Rlogin to encrypt data and protect it from unauthorized use.

Developed by Simon Tatham, this is not only considered as a file transfer tool but also as a terminal emulator and serial console. Since development, the application has been improved by various developers, thereby ensuring that this version is highly complex and advanced.

The tool comes with a Command Line Interface (CLI) known for its ability to manipulate important functions. This program has the look of a comprehensive SSH terminal so that users can easily establish a connection that’s safe for data transfer. It also provides support for all SSH clients, as well as key authentication.

What is PuTTY used for?

Nowadays, many engineers, developers, and system admins need to connect to remote systems regularly. However, Microsoft doesn’t provide a tool for that purpose. This software allows users to connect to switches, routers, mainframes, and servers via SSH and serial clients.

This software is quite handy, especially when working using public internet. It tunnels user sessions using different clients like PSCP, PSFTP, and Telnet—thereby protecting data from prying eyes. It’s also quite useful for text-only sessions.

This program uses various protocols to ensure data doesn’t fall into the hands of hackers and is transferred to its destination without any interruptions. It makes use of cryptography ciphers such as 3DES, DES, Arcfour, and key authentication to ensure the utmost safety and security.

Easy to customize

Once you download and install this on your Windows computer, you will come across an application that is easy to customize. You can change its color, appearance, controls, and behavior. While some users may prefer a graphics UI, this tool offers a CLI—giving experts better control of advanced functions.

Unless you’re a beginner, you can easily configure this for network connections. You can start by specifying the type of connection, destination, hostname, log file, and other details. You can even set aside data that requires verification when being transferred.

This software also offers various settings that give you better control over it. You can choose various emulator options for Terminal Settings, assign functions to different keys, and control proxy usage whenever required. You also have the option to maintain terminal bells and modify advanced features.

Offers terminal emulation

With this tool, you can easily run another operating system on your device. As a terminal emulator, the program allows you to host another OS that you would otherwise not be able to access because of platform constraints. Moreover, the software is quite useful in running Android, Unix, Mac, and iOS applications on your Windows PC.

Ensures data security

When you download this program, it uses cryptography ciphers to ensure that data remains safe and out of the hands of hackers. This free and open-source software is quite reliable and supports a wide range of protocols for secure sharing and connections.

This application also supports the use of authenticator keys to ensure file transfer occurs amidst verified computers. It allows you to generate private or public keys, and use them when sending out sensitive data packets. You can also import existing keys from external sources.

May seem complicated

While this tool has various features, it does have a few drawbacks. One of these is the number of features available, which makes it quite overwhelming for beginners. Another drawback is that it doesn’t support scripting, so developers who prefer to script their sessions may not get what they’re looking for.

Is PuTTY a virus?

No, this program is not a virus. In fact, it is known for its SSH client process by which users can send sensitive information without worrying about hackers.

Is PuTTY safe to use?

The open-source software is devoid of malicious content and is safe to download and use. It offers various security protocols along with cryptography ciphers to ensure data security and integrity.

How do I install PuTTY on Windows 10?

Installing this on Windows 10 is quite straightforward. Once downloaded, open the group of files that you come across and select the application. The program will launch to reveal a configuration window. Here, you’ll have to enter details of your network connection, hostname, and other such details. After that’s done, click on open and start using the program.

Are there any alternatives?

There are many alternatives to this tool, however, not all of them offer the same features as this application. HyperTerminal Private Edition HTPE offers emulation and WinSCP is suitable for data transfers. SecureCRT offers both emulation and data transfer over secure protocols.

Should I download PuTTY?

PuTTY is an open-source software that offers many features. You can use it to emulate another operating system or to transfer data securely, even over a public network. The application uses different file transfer options like SSH, SCP, and Telnet to maintain the integrity of the transfer protocol. For additional security, it supports the use of authenticator keys and cryptography ciphers.

This program ensures that no unauthorized users are accessing sensitive information. The free-to-download application also comes with a command-line interface that is beneficial to advanced users. Therefore, if you’re looking for these functionalities on your Windows device, downloading this tool is a great choice!
