Overview
PuTTY provides several binary files (downloadable from its site), each with a specific function — putty.exe (the SSH client), pscp.exe (SCP), psftp.exe (SFTP), puttytel.exe (Telnet), plink.exe, pageant.exe (SSH authentication agent), and puttygen.exe (key generator). This article describes each.
What are the PuTTY binary files?
You can visit this site to download the following binary files.
PuTTY (putty.exe)
the SSH client itself.
PSCP (pscp.exe)
an SCP client (i.e., command-line secure file copy).
PuTTYtel (puttytel.exe)
a Telnet-only client.
Plink (plink.exe)
a command-line interface for the PuTTY back ends.
Pageant (pageant.exe)
an SSH authentication agent for PuTTY, PSCP, and Plink. It holds your private keys in memory, already decoded, so that you can use them often without needing to type a passphrase.
PuTTYgen (puttygen.exe)
