Thus, programs or subsystems that are based on the SSH protocol will work “out-of-the-box” without having to go through the additional steps of either purchasing or creating the requisite SSL certificate needed for certain modes of secure data transmissions via TLS/SSL. Today, OpenSSH is a default software package found on Unix-like operating systems such as Mac OS X and Linux. In fact, they have several significant differences that are beyond the scope of this article. However, while both protocols provide similar services, they are not the same. The encryption technologies used by both protocols are very reliable, and are (when configured correctly) nearly impossible for hackers to break into. Both are public-key cryptography tunneling protocols that aim to create a secure, confidential exchange of data and connection across a network (particularly the internet). The two most common methods of securely transmitting information between two computers are the (i) Secure Shell (SSH) and (ii) Transport Layer Security (TLS), and its predecessor Secure Sockets Layer (SSL), cryptographic protocols.
