I need to upload a series of files to an FTP server via SFTP. I was planning on using WinSCP and the sample script that they provide here but the FTP server I'm uploading to uses a 1024 .rsa key and a 1024 .dsa key for authentication. The trouble is that WinSCP only accepts Putty's private key format and I've got no influence over converting them or generating new ones.
Considering PowerShell has no built-in SFTP functionality, does anyone know of a'free' way to accomplish this?
Thanks in advance.
