SFTP SSH Key Auth

[patrickhait]

I have set up a SFTP Remote Connection and can successfully place a CSV file on a server through SFTP with Password Authentication.  Our vendor wants to use Public/Private key authentication and has provided us with an ssh_rsa .pub  key.  How can I import that key to our PowerSchool SIS platform?  I have investigated Digital Certificate Management and the Key/User/System Trust Stores, but that seems to be SSL certificates, not SSH keys.  I've tried uploading the SSH key, but it seems that it will only accept a SSL certificate.  One cannot log into SSH via an SSL certificate!  Is there anything can can be done?

Thank you to the tech support team.  Key Store > Public/Private Key Pair.  The trick was that both the public AND the private key had to be .pem files.

Thanks for posting your findings here, it helped me finally find the solution to an SFTP connection using a private key. I could not find any documentation that even mentioned the key certificate alias and how that worked.
