Question 1

What is an SSH known_hosts file?

Accepted Answer

The `known_hosts` file (usually located at `~/.ssh/known_hosts`) is used by the SSH client to store a list of host public keys for SSH servers that the user has connected to. This helps verify the identity of the server on subsequent connections and protect against man-in-the-middle attacks.

Question 2

How do I use this viewer?

Accepted Answer

Click the "Open Local File" button to select a `known_hosts` file from your device. Its content will be displayed as plain text.

Question 3

Is it safe to share my known_hosts file?

Accepted Answer

The `known_hosts` file contains public keys of servers, which are not secret. However, it does reveal which servers you have connected to. This viewer processes files locally, so your data is not uploaded.
