Everything You Need to Know About OpenSSH Server Debian 11 📚
Here is a comprehensive list of everything you need to know about OpenSSH Server Debian 11:
7 Paragraphs – How Does It Work?
OpenSSH Server Debian 11 uses a combination of public and private keys to establish secure connections between two computers. When a user connects to an SSH server, they first send their public key to the server. The server then uses this key to encrypt a session key and sends it back to the user. The user then uses their private key to decrypt the session key and establish a secure connection.
Once the connection is established, users can execute commands, transfer files and perform other tasks securely. OpenSSH Server Debian 11 also provides several security features, including end-to-end encryption, two-factor authentication, and support for FIDO/U2F security keys.
