PuTTY (32-bit)

PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms, along with an xterm terminal emulator. It is written and maintained primarily by Simon Tatham.

PuTTY 32bit is a free and open-source terminal emulator for Windows 11/10 and network file transfer application. Its primary purpose is to provide a secure and reliable way to establish SSH, Telnet, and serial connections to remote servers and devices. The software is renowned for its lightweight nature, cross-platform compatibility, and robust encryption protocols, making it a go-to choice for anyone needing to access remote machines securely.

Main Features

SSH, Telnet, and Serial support: It provides support for secure shell (SSH), Telnet, and serial connections, making it versatile for connecting to various types of systems and devices.

Terminal emulation: It emulates various terminal types, including VT100, VT102, VT220, and xterm, allowing you to work with different systems and applications as if you were using a physical terminal.

Portability: PuTTY is a standalone application and doesn't require installation. You can run it directly from an executable file, making it portable and easy to carry on a USB drive or other storage devices.

Session management: It allows you to save connection details and configurations as sessions, making it convenient to connect to frequently used hosts with specific settings.

Keyboard customization: You can customize keyboard shortcuts, control sequences, and key combinations to suit your preferences and work efficiently within the terminal.

X11 forwarding: It supports X11 forwarding, allowing you to run graphical applications on a remote server and display them on your local system.

Secure connections: It uses encryption for SSH connections, providing a secure way to access remote systems and protect sensitive data during transmission.

Proxy support: It supports various proxy types (HTTP, SOCKS4, SOCKS5) for tunnelling connections through intermediary servers or firewalls.

SCP and SFTP support: The tool includes command-line tools (PSCP and PSFTP) for securely transferring files between your local system and remote servers using SCP (Secure Copy Protocol) and SFTP (SSH File Transfer Protocol).

SSH key management: PuTTYgen, a companion tool, allows you to generate, import, and manage SSH keys for secure authentication.

Configurability: The software offers extensive options and settings to customize your terminal environment, including text colors, fonts, window size, and behavior.

Multiple terminal windows: You can open multiple terminal windows within a single PuTTY instance, making it easy to multitask and manage multiple connections simultaneously.

UTF-8 support: It supports UTF-8 character encoding, enabling you to work with international character sets and languages.

Scripting and automation: It can be used in batch scripts or automated tasks, allowing you to automate repetitive tasks and interactions with remote systems.

Active development: The program is actively maintained and updated by the open-source community, ensuring compatibility with modern systems and security standards.
