RUNNING PUTTY SSH SESSIONS ON UBUNTU SERVER HOW TO

The public part of this pair is used to encrypt data, and only the owner of the private part of the pair can decrypt it. The concept of public key encryption was developed in 1975 by Whitfield Diffie and Martin Hellman and is based on using a pair of keys: one private key and one public key. SSH key-based authentication uses asymmetric encryption to add an extra layer of security to remote access to a system. SSH key-based authentication helps to address this weakness. If an attacker learns the password, the system becomes vulnerable. The weakness of the basic implementation is that it depends entirely on the strength of the passphrases assigned to accounts.

All communications between the client and server are encrypted to prevent unauthorized parties from intercepting data. For example, you can use a client running on Linux, Windows, or macOS to connect to a server running on Ubuntu. The server runs on the system to which you need to connect.Ī significant advantage is cross-platform.

The client runs on the computer that establishes the connection. The basic configuration consists of a client and a server. You can use it to access the shell and transfer data. Secure Shell provides a secure remote connection to the operating system.

In the article below, we'll look at SSH keys and how to connect to a remote server, for example, a Hostman one. We recommend configuring SSH keys to protect your system from unauthorized access.

However, there are higher levels of security. By default, you use a password to connect to a server via Secure Shell (SSH).
