PuTTY是一个Telnet/SSH/rlogin/纯TCP以及串行阜连线软件。较早的版本仅支援Windows平台,在最近的版本中开始支援各类Unix平台,并打算移植至Mac OS X上。除了官方版本外,有许多非官方的团体或个人将PuTTY移植到其他平台上,像是以Symbian为基础的移动电话。

PuTTY为一开放源代码软件,主要由Simon Tatham维护,使用MIT licence

PuTTY 0.63 主要是安全方面的问题修复,包括:

  • Security fix: prevent a nefarious SSH server or network attacker from crashing PuTTY at startup in three different ways by presenting a maliciously constructed public key and signature.
  • Security fix: PuTTY no longer retains the private half of users' keys in memory by mistake after authenticating with them.
  • Revamped the internal configuration storage system to remove all fixed arbitrary limits on string lengths. In particular, there should now no longer be an unreasonably small limit on the number of port forwardings PuTTY can store.
  • Port-forwarded TCP connections which close one direction before the other should now be reliably supported, with EOF propagated independently in the two directions. This also fixes some instances of port-forwarding data corruption (if the corruption consisted of losing data from the very end of the connection) and some instances of PuTTY failing to close when the session is over (because it wrongly thought a forwarding channel was still active when it was not).
  • The terminal emulation now supports xterm's bracketed paste mode (allowing aware applications to tell the difference between typed and pasted text, so that e.g. editors need not apply inappropriate auto-indent).
  • You can now choose to display bold text by both brightening the foreground colour and changing the font, not just one or the other.
  • PuTTYgen will now never generate a 2047-bit key when asked for 2048 (or more generally n−1 bits when asked for n).
  • Some updates to default settings: PuTTYgen now generates 2048-bit keys by default (rather than 1024), and PuTTY defaults to UTF-8 encoding and 2000 lines of scrollback (rather than ISO 8859-1 and 200).
  • Unix: PSCP and PSFTP now preserve the Unix file permissions, on copies in both directions.
  • Unix: dead keys and compose-character sequences are now supported.
  • Unix: PuTTY and pterm now permit font fallback (where glyphs not present in your selected font are automatically filled in from other fonts on the system) even if you are using a server-side X11 font rather than a Pango client-side one.
  • Bug fixes too numerous to list, mostly resulting from running the code through Coverity Scan which spotted an assortment of memory and resource leaks, logic errors, and crashes in various circumstances.
