Re: sftp from IBMi to remote server

I know that the private key needs to be secured but with an ssh key exchange connection the partner needs your public key in their authorized_keys file and the partner's RSA fingerprint needs to be in your known_hosts file.

Given that probably any system is breakable the ssh key exchange offers a pretty good solution.

True? It is on our system.

Yes, mostly true. See comment from John.

Let's put it this way: If anybody copies the ssh private key, he can also utilize that one for abuse. Ssh-Keys for automation are most often not protected by passwords, so automation doesn't need passwords to be supplied. Thus, the key is unencrypted and ready for use.

In general, it's possible to use ssh-agent. This is a background task to which you can add encrypted (password protected) keys and these will be stored in memory in unencrypted form. (I'm doing that manually after reboots.) Through environment variables, ssh clients (sftp, scp, ssh) and ssh-add (for adding keys) find a local socket for communicating with the ssh-agent. Honestly, I don't know how much of this Linux/Unix specific stuff also applies to PASE, though.
