Using PuTTY with CryptoCards

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 PuTTY suite of software includes:

  • PuTTY (the Telnet and SSH 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)

The latest version is available for download at:

1) Open up PuTTY and put in the Host Name field and check the SSH button underneath it.

2) Click on the SSH tab in the left panel and select "2" for the "Preferred SSH protocol version".

3) Click on the Auth tab under the SSH tab and make sure that "Attempt keyboard-interactive authentication (SSH2)" is checked.
