SSH Vs SSL/TLS - What is the difference between them

What is the difference between SSH Vs SSL ? Is that same question arises in your mind also and still confused among that. Then don't worry it pretty obvious because that both are Security Protocol and in sometime it very similar.

So don't worry we will be covering very detailed comparison between SSH Vs SSL Side by Side and we also check some of their basic tasks, similarity and How they Work.

So Let's Start !

What is SSL

   

SSL that is Stand for Secure Socket Layer is a Network Protocol. That is use to Securely transmitting data over internet with help SSL Certificate.

Now a day SSL is replaced by TLS (Transport Layer Security) Which Successor of SSL 2.0 and 3.0.

Use Case of SSL

• Protect Online Transaction.
• Protect Sensitive data over Internet.
• Protect Email client and Email Server Connection.
• Protect Files Transfers over Https and FTP.

How SSL Work

As we know, Basic task of SSL/TLS is to protect our data when it transiting over internet from Malicious Attackers over internet. For SSL use SSL Certificate. That performs two major task that is Authentication and Data Encryption.

If you're wondering How to Install SSL for Free on your Website then check out previous post.

Authentication

In Authentication process before encrypted connection is established via SSL protocol between Client and Server. For that Browser must first confirm the identity of the website. To identify the website it use Websites SSL certificate to Verify it issued by Third-party Certificate Authority.

The Reason why it's crucial because if Browser doesn't Verify identity and established connection with boughs site or Malicious client then there is no use any other Security measures like Data Encryption.

Data Encryption

Data Encryption is way of Converting simple text or data( Human readable form) to Cypher text(Machine Readable). This process of converting text or data into Cypher text is called as Encryption and process of converting Cypher text again back to normal text called as Decryption. All this process of Encryption is done with help Key Pair. As it's it has one Public Key that publicly available and second Private Key that stored privately on Secure Serve.

Whenever data is transmitted over the network it encrypted with help Public Key and transmits it to opposite device and that device Decrypt that massage with help of that private Key.

What is SSH

SSH that is Stand for Secure Shell is Network Protocol. That allows user to Securely Access Remote Computer or Server over Unsecured Network (Internet) Remotely from any location.

Use Case of SSH

• Provide Secure Remote access to user.
• Provide Secure Remote to System Administration to Run Commands on Shell.
• Allow Secure File Transfers over Network.

How SSH Works

One of the main reason why the people ask about SSH Vs SSL is that both of this protocol has some major common feature in both of it. 

That is Authentication or Data Encryption. The Difference is that both are use for different purposes like SSL provide Secure connection between Client where SSH provide Secure Remote Access to System Administration to perform Command execution, uploaded file, Give Right to Access over Remote device, etc.

SSH comes in place when Telnet, FTP and rlogin are not providing secure Login Method. SSH comes as Alternative of that with help Data encryption and Authentication.

SSH Vs SSL: Side by Side Comparison

SSH	SSL
SSH Stands For Secure Shell	SSL Stands For Secure Socket Layer
SSH is Network Cryptographic Protocol	SSL is Security Protocol
Used to Securely Access Remote Computer or Server	Used established Secure connection between Client and Server to transmit data over Network.
SSH use server verification, session key generation, and client	SSL Certificate is used for Authentication
SSH use Network Tunnel	SSL use SSL Certificate
Secure user from DNS spoofing, IP source routing, data manipulation, data sniffing during transmission, Spoofing of IP addresses, etc	Secure user from Malicious Attackers
SSH use Port 22 to make Secure connection	SSL use Port 443 to make Secure connection

Conclusion

As far know we know that SSL/TLS and SSH are both Network Protocol and use Data encryption and Authentication process to establish Secure connection and Secure Login Method. Both this protocol are very similar in nature but it has different task to perform.

So now I hope all of you now clear about SSL/TLS Vs SSH Comparison.
