SSH keys are required when using SFTP with Key File or SFTP with 2-Factor Authentication in EFTXpress. Keys are generated using the Windows command prompt.

Step 1: Open Command Prompt

Press the Windows key, type cmd and press Enter.

Step 2: Generate the key pair

Type the following command and press Enter:

ssh-keygen -m PEM

This generates a public/private RSA key pair.

Step 3: Specify the key file path

When prompted, enter a file path, for example:
C:\SFTPKeys\CompanyName\id_rsa
Keep your private key secure and do not share it.

Step 4: Enter a passphrase

Enter a password when prompted and confirm it. If no password is required, press Enter twice to skip.

Step 5: Acknowledge key creation

You will receive confirmation messages when keys are successfully created.

Step 6: Locate your keys

Go to the directory specified in Step

3. You will find two files:

  • id_rsa - private key (keep this secure, never share)
  • id_rsa.pub - public key (provide this to your SFTP server, e.g. Rebex)

Configuring keys in EFTXpress:

Navigate to Setup EFTXpress Banks | SFTP Setup tab and enter:

  • Private Key File Name: full path to your id_rsa file, e.g. C:\SFTPKeys\CompanyName\id_rsa
  • Key Password: the passphrase entered during key creation

Select Test Connection to verify the setup.
