1. SFTP Public Key-based
Authentication
Stat 5.1.2 introduces the ability to configure SFTP authentication using public
key infrastructure (PKI). This document describes the background and
configuration of this feature.
Whenever Stat accesses file objects on a file server, Stat logs in using the
username configured in Stat for that server. The file server then authenticates
the user ID, typically with a password. For customers wanting a more secure
method of authenticating user accounts on their SFTP file servers, Stat 5.1.2
supports public key-based authentication.
With public key-based authentication, each user ID has a set of public keys
which are authenticated by a set of corresponding, mathematically related
private keys. Data encrypted with public keys can only be decrypted by their
associated private keys and vice versa. When the user (in this case Stat)
attempts to log into a SFTP server, the user ID is sent to the server with an
associated public key. The server then
