For example, in kernel development access via a serial port is still sometimes the best way to debug a panic that causes an immediate reboot, as it provides a way to see the boot messages. These can sometimes be useful for debugging purposes and for working with some legacy devices. PuTTY also supports connecting to serial ports and raw sockets. There cannot be cybersecurity in a networked environment without encryption. Even the most oppressive countries need to secure their systems somehow. Most systems can no longer be managed without encryption. However, SSH is now used in all countries, officially or unofficially. There is a separate version of the software, called PuTTYtel, for countries that do not allow any use of encryption. Compromised routers, switches, or ARP proofing attacks can also be used to inject arbitrary commands into telnet sessions. That was the very problem SSH was designed to solve.

By mid-1990s, such password sniffing attacks had become the largest security problem on the Internet. It is very easy to listen to network traffic and steal user names and passwords from telnet traffic. Telnet sends all user names and passwords in the clear. Its use is not recommended for security reasons. However, very few devices use telnet these days. Universal SSH Key Manager a popular SSH key management solution and the only one at the time of this writing that supports. Recently, Wikileaks obtained CIA hacking tools designed to steal SSH keys and their passphrases. This happened, for example, in the infamous Sony breach. It is common for hackers and malware to collect SSH keys when penetrating an organization. The PuTTYgen tool can be used for generating new keys and converting between. PuTTY uses its own file format for SSH keys. WinSCP can now import PuTTY profiles, but separate login is still required for each.

Having two software packages, switching between them to do operations, and managing profiles and logins for both is extra trouble. The WinSCP and FileZilla clients can also be used for file transfers in conjunction with PuTTY. Tectia SSH, for example, has offered fully integrated file transfer capability since 2000. However, most non-technical users are not willing to use a command line. However, command-line tools called PSFTP and PSCP are provided. The user interface does not include an integrated file transfer client.

The PuTTY terminal is pretty good and handles terminal emulation well. SSH, telnet, and plain TCP/IP protocols are supported. It has good terminal emulation, good configurability, and good support for different cryptographic algorithms. The main feature of the product is the terminal window. No scripting support, but can be used together with WinSCP.

Supports public key authentication and Active Directory/Kerberos authentication.ДЇile transfers only using a separate command-line programs. Practically all devices support SSH2 these days. Note that use of SSH1 is not recommended for security reasons. Both SSH2 and SSH1 protocols are supported. Supports SSH client, telnet client, SFTP client (command line only), and rlogin client. An MSI installer has been available since 2016. Setting up SSH keys on Linux with PuTTYgen Setting up SSH keys on Windows with PuTTYgen For Windows and IBM z/OS mainframes, we recommend the Tectia SSH server. PuTTY also does not include an SSH server. Instead, file transfers have to be done via the command line. A major shortcoming of PuTTY is that it does not have integrated file transfers in the client itself. There many SSH clients that are more modern.
