So we were trying to transfer files from unix server to a windows server 2003. I currently don't have any visibility on the unix server since it is being handled by another team. So in order for the 2 servers to establish connection, they sent us a public key which they said that we need to register on our windows server 2003 machine. can anyone help me? i cant seem to find anything about registering this public key generated by putty on a windows server 2003. there's no directory to put the public key(like in linux authorized_keys). Any help will be appreciated. thanks in advance.

EDIT: we're trying to transfer file via pscp if this info is needed.
