PuTTY is a free computer program that helps you connect to other computers. It's like a special window that lets you send commands to another computer. This is super useful for managing servers or other devices from far away.
PuTTY can connect using different ways, called network protocols. These include SSH for secure connections and Telnet for older ones. It can also help you transfer files securely.
This program was first made for Microsoft Windows computers. But now, you can use it on many other operating systems too. These include Linux and macOS. PuTTY was created by a British programmer named Simon Tatham. The name "PuTTY" doesn't have a special meaning.

What PuTTY Can Do
PuTTY has many features that make it useful for connecting to other computers. It helps you connect safely and control how your connection works.
Secure Connections
PuTTY is great for making secure connections. It uses something called SSH to keep your information private. This means no one else can easily see what you are doing.
You can choose how PuTTY keeps your connection safe. It uses special codes, like a secret language, to protect your data. PuTTY also lets you use special keys to prove who you are. This is like using a digital ID card.
Working with Different Systems
PuTTY can act like different types of old computer terminals. This helps it work with many kinds of computer systems. It can also help you send information from one computer to another. This is called port forwarding.
PuTTY works with modern internet connections, including IPv6. It can also connect to devices using a serial port. This is a way to connect directly to some hardware.
Extra Tools for Files and Commands
PuTTY comes with other helpful programs. These are command-line tools, meaning you type commands to use them.
- PSCP helps you copy files securely between computers.
- PSFTP is another tool for transferring files securely. It's like a secure version of FTP.
- Plink lets you run commands on a remote computer without opening the main PuTTY window.
PuTTY itself doesn't have tabs for multiple connections. But other programs can add this feature to PuTTY.
How PuTTY Started
The development of PuTTY began in late 1998. By October 2000, it was already a useful program. It could connect using SSH-2, which is a secure way to connect computers.
Parts of PuTTY
PuTTY is actually a collection of several tools that work together. Each part has a specific job.
- PuTTY: This is the main program. It connects to other computers using Telnet, rlogin, or SSH. It can also connect to a serial port.
- PSCP: This tool helps you copy files securely from one computer to another.
- PSFTP: This tool is for transferring files securely, similar to how FTP works.
- PuTTYtel: This is a simpler version of PuTTY that only uses Telnet connections.
- Plink: This tool lets you run commands on a remote computer from your command line. It's often used for secure connections.
- Pageant: This program helps you manage your secure keys. It remembers your keys so you don't have to type them every time.
- PuTTYgen: This tool helps you create new secure keys. These keys are used for secure connections.
- pterm: (Only for Unix computers) This is a special window that acts like a terminal. It works just like the main PuTTY program.
