SSH vs. SSL: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 1, 2024
SSH (Secure Shell) is a protocol for secure remote login and command execution, while SSL (Secure Sockets Layer) is a standard for encrypting data in transit, used widely in secure web communications.

Key Differences

SSH is a network protocol designed for securely accessing and managing devices remotely. It allows encrypted communication sessions over potentially insecure networks. SSL, on the other hand, is a standard security technology for establishing an encrypted link between a web server and a browser, ensuring that all data passed between them remains private.

SSL encrypts the data transferred over the internet to protect it from eavesdropping, which is crucial for protecting sensitive information in web transactions. SSH provides a secure channel over an unsecured network by using a client-server model, enabling users to securely access a server or other network services.

In terms of usage, SSH is commonly used by system administrators for controlling servers remotely. It encrypts the session to keep the communication confidential. SSL is primarily used to secure data transfers on the internet, such as credit card transactions, data transfer, and logins, by encrypting the connection.

Both SSH and SSL use public key cryptography for secure communications. However, while SSL is used more broadly on the internet for securing connections, SSH is specifically used for secure remote logins and file transfers, like in SSH File Transfer Protocol (SFTP).
