Hi There, so our IT Department is now implementing a 'no password' policy with using our organization's (s)ftp sites. WinSCP does provide a method to use the key file generated by OpenSSH (please see attached screengrab)...but I can not see a method for leveraging this file in FME's FTPCaller...is this true? (so no way to do this in FME?). Thanks for any thoughts here.
Solved
Does FTPCaller provide a method for using OpenSSH key files?

Hello @louielou1234
I would recommend taking a look at the following article https://community.safe.com/s/article/Using-a-private-SSH-key-with-FTPCaller-to-authenticate-an-SFTP-Connection-on-FME-Server-and-FME-Desktop
The private SSH key in your screenshot is a .ppk, which means it is a Putty Private Key (PPK). So you would use Putty's authentication agent, Pageant, instead of OpenSSH utilities. OpenSSH private keys do not have a file extension. I hope this information helps.

Hi Debbiatsafe again,
Sooo... it turns out that I am able to run the workbench in FME for Desktop (2022.1) just fine and great, but unfortunately when I try to run it from FME for Server (FME Server 2022.1.2 Build 22627 ) I get the error: 'FTP/FTPS/SFTP transfer error: Login denied'. --I did try changing some parameters (like 'Passive' to 'Active' Mode) but still no luck :( ....one note might be that FME Server now runs under my personal Active Directory domain account --as that was the only way we could get FME Server to work with ArcPro 3.x operations due to the new Named-User licensing model ESRI now requires....and I mention this because when I created the SSH Key Files with Putty I was logged into the machine that we run FME Server from as me... Any thoughts or troubleshooting tips would be super appreciated! Thanks very much again. Louie.

Hello @louielou1234
Thanks for the screenshot. The key in the screenshot looks more like a public key instead of a PuTTY private key. When viewed In a text editor, a PuTTY private key should start with:
PuTTY-User-Key-File-2: ssh-rsa
Encryption: aes256-cbc
Comment: ...Are you able to confirm you are using the same private key on Desktop and Server?
In addition, the SSH key pair cannot be generated with a passphrase as there is no way to automate entering the passphrase on FME Server.
