The list of paths to trusted SSH key files controls the public / private key authentication that SFTP allows for. This setting does not want you to enter in a 'trusted keys file', or a folder path, but rather the path to the actual key file itself. So '/files/keys/' is bad, while '/files/keys/' would be OK. Separate multiple items with new lines. Most SSH key formats are supported.


There is also a more generic way to use this field. If the key file has the exact name of the user logging in, you can instead reference the directory '/files/keys/'. In this case there would need to be a file named 'ben' in that directory.

OS X or Linux

Generate a key pair by issuing this command in a Terminal window:

ssh-keygen -t dsa

Take the resulting public key and point CrushFTP to it as described above.


If you are unsure of how to generate a public / private key pair for your SFTP client, you may want to take a look at puttygen for Windows to generate the keys. CrushFTP can use the public key file you generate.
