What is sshd-keygen-wrapper?

Sshd-keygen-wrapper is a tool built into macOS. Its function is precisely what its name suggests: generating SSH keys. SSH, or Secure Shell, is a protocol that allows secure remote access to your Mac from another computer. When you enable remote access features like Screen Sharing, sshd-keygen-wrapper springs into action behind the scenes. It creates unique SSH keys for your Mac, acting as a digital passport that identifies your device to incoming connections.

How does it work?

SSH relies on cryptographic keys to verify the identity of devices trying to connect. sshd-keygen-wrapper plays a crucial role in this process. Here’s a breakdown:

  • Key generation: If your Mac doesn’t already have SSH keys, sshd-keygen-wrapper creates them. These keys are like a digital handshake that ensures only authorised devices can connect.
  • Secure communication: The generated keys encrypt communication between your Mac and the remote device. This encryption jumbles up the data, rendering it indecipherable to unauthorised individuals trying to eavesdrop on the connection.


Why is it listed in Full Disk Access?

Sshd-keygen-wrapper appears in Full Disk Access because it needs permission to access your entire disk. This access is essential for tasks like generating and securely storing SSH keys.

Should I be worried?

Absolutely not. Sshd-keygen-wrapper is a legitimate and essential part of MacOS. It enhances security by ensuring that only authorised users can access your Mac remotely.

Do I need to keep it enabled in Full Disk Access?

If you plan on using remote access features like Screen Sharing or SSH, it is recommended that you keep sshd-keygen-wrapper enabled in Full Disk Access. Disabling it might hinder your ability to connect to your Mac remotely.

Sshd-keygen-wrapper is a vital component for secure remote access on your Mac. While its name might sound intimidating, understanding its purpose can help you to make informed decisions about your Mac’s security settings. So, the next time you see sshd-keygen-wrapper, remember it’s not malware but an important and legitimate macOS tool safeguarding your Mac’s remote access.
