||Please follow the steps below:
1) Use an application like the "SSH-keygen" in order to generate a pair of keys: private key and public key.
2) Add the content of the new public key to the "authorized keys" file on the host.
3) In PowerTerm`s "Connect" window: set the "security type" to "SSH" and click "Details"
4) Set "Private key file for authentication" to the exact location of the private key generated in step #1. The private key does not have to be *.epk file. When doing so - PowerTerm will automatically create a new private key in EPK format.
