Key File Setup

Generating Keys in 6 Steps

The following steps outline the process of configuring the SFTP system by generating SSH keys using the Windows key generator - ssh-keygen -m PEM

Step 1: Command Prompt

Open the Windows Command Prompt by pressing the Windows key, typing "cmd," and press Enter.

Step 2: Key Generation

In the command prompt to generate the SSH key, use the following command: ssh-keygen -m PEM and press Enter.

This will generate public/private rsa key pair.

Step 3: Specify Key File Path

Upon prompt, enter a file path (e.g., C:\SFTPKeys\JohnSmith\id_rsa) and press Enter.

Ensure that you securely manage your private key and do not share it. The public key can be provided to the SFTP server for secure authentication.

Step 4: Enter Passphrase

Enter a password when prompted, and press Enter. Confirm the password by entering it again and pressing Enter. If a password is not required, press Enter and confirm by pressing Enter again.

Step 5: Acknowledge Key Creation

Upon completion, you will receive messages indicating successful key creation.

Step 6: Navigate to Key Directory

Go to the specified directory where keys are stored (C:\SFTPKeys\JohnSmith).

Ensure you have two keys:

• id_rsa (keep secure)
• id_rsa.pub (share as needed with Rebex)

Testing the SFTP Setup

You can use the Test button to test the SFTP setup.

The file ‘’PSEFTTRFRTEST.TXT’’ will be created when selecting the Test button and uploaded.

A message will be displayed if the upload is successful or failed. The log file ‘’PSEFTSecure.log’’ will be updated. This file is in the cbXX directory. Check the log file if the Test failed.

Note: A common error when using SFTP with key file is to use the wrong key file or a key file in the wrong format. See Key file setup.
