Here are the PuTTY files themselves:
PuTTY (the SSH and Telnet client itself)
PSCP (an SCP client, i.e. command-line secure file copy)
PSFTP (an SFTP client, i.e. general file transfer sessions much like FTP)
PuTTYtel (a Telnet-only client)
Plink (a command-line interface to the PuTTY back ends)
Pageant (an SSH authentication agent for PuTTY, PSCP, PSFTP, and Plink)
PuTTYgen (an RSA and DSA key generation utility).
LEGAL WARNING: Use of PuTTY, PSCP, PSFTP and Plink is illegal in countries where encryption is outlawed. We believe it is legal to use PuTTY, PSCP, PSFTP and Plink in England and Wales and in many other countries, but we are not lawyers, and so if in doubt you should seek legal advice before downloading it. You may find useful information at cryptolaw.org, which collects information on cryptography laws in many countries, but we can't vouch for its correctness.
Use of the Telnet-only binary (PuTTYtel) is unrestricted by any cryptography laws.
There are cryptographic signatures available for all the files we offer below. We also supply cryptographically signed lists of checksums. To download our public keys and find out more about our signature policy, visit the Keys page. If you need a Windows program to compute MD5 checksums, you could try this one at pc-tools.net. (This MD5 program is also cryptographically signed by its author.)
