The aim of this vbs script is to launch putty using an URL like ssh://login@host directly from a browser. The .bat is almost the same than .vbs but less robust and just their for older systems.

putty.bat

:: This version is not as powerfull as vbs version, please prefere the other one.
:: It's just there if you need a non-visual basic way to perform this.
:: Restrictions:
::   - Password cannot contain a % or finish with @
::   - Chrome adds a / at the end of the URL, not yet managed

:: The aim of this script is to execute putty with parameters like ssh://login@host 
:: Installation:
::   - Launch putty.reg to associate ssh:// and telnet:// to this script
::   - Edit the putty path in parameter below like puttyPath="C:\Program Files (x86)\putty.exe"
::   - Save this .bat on your PC like c:\putty.bat (or change the path in putty.reg)
:: Uninstallation:
::   - Run unputty.reg
