In this section of our blog, we will understand how SSH works. Let us understand the technical breakdown of SSH.
Key Exchange and Encryption
Before starting communication, SSH performs a secure key exchange between the client and server. The server provides its public key in response to a connection request made by the client. To establish a secure communication channel, the client generates a session key and sends it back encrypted with the server’s public key. The basis for encrypting the ensuing data transmission is this encrypted session key.
Authentication
An essential part of the SSH operation is authentication. Users can authenticate themselves using various techniques, including the more secure key-based authentication or the conventional username/password combo. In the latter case, users have two cryptographic keys: a matching public key shared with the server and a private key safely kept on their client computer.
Session Multiplexing
SSH allows multiplexing, which enables many communication channels to run over a single encrypted connection to maximize resource use and boost efficiency. As a result, users can handle multiple tasks at once inside a single SSH session.
Port Forwarding
Port forwarding takes the front stage in extending SSH’s reach. While remote port forwarding enables the server to forward a remote port to a different port on the client, local port forwarding provides secure access to services on a remote server. This fosters secure access to local services much easier.
X11 Forwarding Process
SSH shows off its graphical capabilities by enabling users to run and view local graphical apps on a remote server. This operation makes it possible to communicate with graphical interfaces without issues through a secure SSH connection.

How SFTP Works: Technical Breakdown
Before moving toward the SFTP vs SSH debate, we will now understand the working procedure of SFTP in detail.
Establishing a connection and verifying identity
Initiating an SFTP connection involves a negotiation between the client and the server. During this process, the server requests the user’s authentication credentials to verify the identity.
Change of Encryption Keys
Following authentication, a key exchange is conducted between the client and server to create a secure communication channel. Encrypting the data during transmission requires creating a shared secret, also known as a session key.
Encryption of Data
Once the secure communication channel is established, SFTP ensures that the files being transferred are safe from prying eyes or illegal access by encrypting the data using the pre-established session key. This encryption safeguards the data by traveling through a secure tunnel.
File Operations and Command Execution
The client and server can exchange commands for different file actions once the secure channel has been created. Requests to upload, download, remove, or list files and directories on the server are examples of these commands.
Integrity Checking through Hashing
SFTP computes hash values for the transferred files using hashing methods before and after the data transfer. Through this method, the recipient can compare the hash values to confirm the integrity of the files they received.
Logging and Error Handling
SFTP keeps detailed logs of the file transfer procedure. Information concerning user actions, mistakes, and other pertinent occurrences may be included in these logs. These logs are also essential for auditing, debugging, and tracking file transfer activities.
Termination of Connection
The SFTP connection is safely closed after the file transfer is finished or the user chooses to disconnect. A smooth conclusion to the secure session is ensured by releasing resources and closing the encrypted channel.
