Zertifikatsanmeldung an sftp-Server

To authenticate against an SFTP (SSH File Transfer Protocol) server using a certificate, you typically need an SSH key pair consisting of a private key and a corresponding public key. The private key remains on your local system, while the public key is uploaded to the SFTP server for authentication.

Here’s a general outline of the process:

  1. Generate an SSH key pair: Use a tool like ssh-keygen (available on most operating systems) to generate a key pair. This command typically generates a private key file (e.g., id_rsa) and a public key file (e.g., id_rsa.pub). Example command: ssh-keygen -t rsa -b 4096
  2. Provide the public key to the SFTP server: The public key needs to be added to the server’s authorized keys file. This process depends on the specific server and its configuration. It may involve copying the public key contents into a specific file or using an administration interface to upload the key.
  3. Configure your SFTP client: In your SFTP client application (e.g., FileZilla, WinSCP, or command-line tools like sftp or scp), you’ll need to specify the private key file for authentication. The exact method of configuring this varies depending on the client you’re using.
  • In graphical SFTP clients: Look for an option to configure SSH keys or identity files. Provide the path to the private key file there.
  • In command-line clients: Use the -i flag followed by the path to the private key file. Example command: sftp -i /path/to/private_key user@server
  1. Connect to the SFTP server: With the private key configured, initiate a connection to the SFTP server using your client. It should use the private key for authentication and establish a secure connection.

It’s worth noting that the specific steps may differ depending on the SFTP server software, client application, and operating system you’re using. It’s recommended to refer to the documentation or guides provided by your server and client for detailed instructions specific to your setup.
