every 2 years a vendor we have sends us a new asc key for encrypting files and transferring to their site. But each time we always run into an issue converting the ASC key to a putty ppk file to use with winsc.
We are getting an error of “missing putty header” and the vendor is less than helpful on helping us convert it.
Looking for suggestions/help on getting the asc key converted to a putty ppk key??
