SFTP C# library with PuTTY private key (PPK) support

I need a C# library that allows to send files to a SFTP server and that it accepts private keys in PuTTY format (PPK).

Does anyone know of such a library?

Solution

  • You can try WinSCP .NET assembly (C# wrapper around WinSCP scripting interface):

    Its SessionOptions.SshPrivateKeyPath accepts a path to .ppk file.

    (I'm the author of WinSCP)

    Or you can use PuTTYgen to convert the .ppk private key file to a format supported by your preferred SSH/SFTP library.
