PuTTY is an SSH and telnet client. PuTTY supports many variants of secure remote terminals and provides users with control over SSH encryption keys and protocol versions, alternative passwords (such as AES, 3DES, RC4, Blowfish, DES, and public key authentication). PuTTY uses its own key file format-PPK (protected by message verification code).  PuTTY supports SSO through GSSAPI, including the GSSAPI DLL provided by the user. It can also simulate control sequences from xterm, VT220, VT102, or ECMA-48 terminal emulation, and allows the use of SSH for local, remote or dynamic port forwarding (including X11 forwarding). This program is about the tips and tricks of PuTTY configuration.
