PuTTYgen is a key generator. It generates pairs of public and private keys to be used with PuTTY, PSCP, and Plink, as well as the PuTTY authentication agent, Pageant (see chapter 9). PuTTYgen generates RSA and DSA keys.
When you run PuTTYgen you will see a window where you have two choices: ‘Generate’, to generate a new public/private key pair, or ‘Load’ to load in an existing private key.

④
PSFTP, the PuTTY SFTP client, is a tool for transferring files securely between computers using an SSH connection.
PSFTP differs from PSCP in the following ways:
- PSCP should work on virtually every SSH server. PSFTP uses the new SFTP protocol, which is a feature of SSH-2 only. (PSCP will also use this protocol if it can, but there is an SSH-1 equivalent it can fall back to if it cannot.)
- PSFTP allows you to run an interactive file transfer session, much like the Windows
ftp
program. You can list the contents of directories, browse around the file system, issue multipleget
andput
commands, and eventually log out. By contrast, PSCP is designed to do a single file transfer operation and immediately terminate.
⑤ pscp
PSCP, the PuTTY Secure Copy client, is a tool for transferring files securely between computers using an SSH connection.
⑥
Plink (PuTTY Link) is a command-line connection tool similar to UNIX ssh
. It is mostly used for automated operations, such as making CVS access a repository on a remote server.
Plink is probably not what you want if you want to run an interactive session in a console window.
⑦pageant
Pageant is an SSH authentication agent. It holds your private keys in memory, already decoded, so that you can use them often without needing to type a passphrase.
This list summarises some of the differences between SSH, Telnet and Rlogin.
- SSH (which stands for ‘secure shell’) is a recently designed, high-security protocol. It uses strong cryptography to protect your connection against eavesdropping, hijacking and other attacks. Telnet and Rlogin are both older protocols offering minimal security.
- SSH and Rlogin both allow you to log in to the server without having to type a password. (Rlogin's method of doing this is insecure, and can allow an attacker to access your account on the server. SSH's method is much more secure, and typically breaking the security requires the attacker to have gained access to your actual client machine.)
- SSH allows you to connect to the server and automatically send a command, so that the server will run that command and then disconnect. So you can use it in automated processing.
