    How-To use an X.509 Certificate for SFTP Public Key Authentication

    In version v2020.4.11.0 we added X.509 Certificate support for SFTP Public Key Authentication.

    Some FAQ:

    • SFTP authentication using private keys is generally known as SFTP Public Key Authentication. So we need a private key file in the SFTP Setup.
    • As default we first try to load the RSA/DSA private key from the file.
    • If this doesn’t work we’ll try to import the file as X.509 Certificate.

    Authentication with an X.509 certificate is possible in two modes:

    • Full: The certificate is sent to the server. This assumes the server can handle certificate authentication. Set ‘Cert Auth Mode’ to ‘Auto’ (= default).
    • Key-Only: Only the keypair is used. This works with servers that don’t support certificates. Set ‘Cert Auth Mode’ to ‘Raw Public Key’.
