Download PuTTY 0.75

A new release of PuTTY has become available. PuTTY is one of the most popular telnet and ssh clients, which allows remote management of a computer over a secure connection. Originally, the program was only available for Windows, but today there are also clients for the various Unix platforms. The changelog for version 0.75 can be found below.

These features are new in 0.75:

• Security fix: on Windows, a server could DoS the whole Windows GUI by telling the PuTTY window to change its title repeatedly at high speed.
• Pageant now supports loading a key still encrypted, and decrypting it later by prompting for the passphrase on first use.
• Upgraded default SSH key fingerprint format to OpenSSH-style SHA-256.
• Upgraded private key file format to PPK3, with improved passphrase hashing and no use of SHA-1.
• Terminal now supports ESC[9mforstrikethroughtext[9mforstrikethroughtext
• New protocols: bare ssh-connection layer for use over already-secure IPC channels, and SUPDUP for talking to very old systems such as PDP-10s.
• PuTTYgen now supports alternative provable-prime generation algorithm for RSA and DSA.
• The Unix tools can now connect directly to a Unix domain socket.
