PuTTY: A Free Telnet/SSH Client
PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an
xterm terminal emulator. It is written and maintained primarily by Simon Tatham.
The latest version is beta 0.58.
LEGAL WARNING: Use of PuTTY, PSCP, PSFTP and Plink is illegal in countries where encryption is outlawed. I believe it is legal to use PuTTY, PSCP, PSFTP and Plink in England and many other countries, but I am not a lawyer and so if in doubt you should kosmetik-beratung.org seek legal advice before downloading it. You may find this site useful (it's a survey of cryptography laws in many countries) but I can't vouch for its correctness.
Use of the Telnet-only binary (PuTTYtel) is unrestricted by any cryptography laws.
2006-03-31 Proposed withdrawal of Alpha NT PuTTY
From the next release, we propose to stop providing binaries for PuTTY on Windows NT on the Alpha processor. Our own original need for PuTTY on Alpha NT has gone, and our logs suggest that nobody else now uses it. If this is a problem for you, let us know.
2005-06-09 Problems with 0.58 and Windows XP
We're getting occasional but persistent reports that the latest release, 0.58, fails to run on some versions of Windows XP (particularly pre-SP2), giving an "application configuration is incorrect" error message. The cause is known, and a variety of workarounds are described on the associated bug page.
2005-02-20 SECURITY HOLE, fixed in PuTTY 0.57
PuTTY 0.57, released today, fixes two security holes which can allow a malicious SFTP server to execute code of its choice on a PSCP or PSFTP client connecting to it. We recommend everybody upgrade to 0.57 as soon as possible.
2004-12-23 Trojan PuTTY installer circulating
We've been alerted to a trojan PuTTY 0.56 installer that was posted on CNET's download.com for about a fortnight (now removed). We are informed it installed various spyware.
The file length was 509860 bytes (much shorter than any installer we've ever released) and the md5sum was 49550e478e9dd008998c2c5294a884c5.
We'd like to take this opportunity to encourage everyone to verify the signatures of PuTTY downloads before executing them. Details are on our Keys page.
