HTTPS vs. SSL: The Details

learn about ssl vs https

Hypertext Transfer Protocol Secure (HTTPS), Secure Socket Layer (SSL), and Transfer Layer Security (TLS) are common internet security protocols. These frameworks are used to secure data and communications in internet connections.

The World Wide Web comprises endless connections between servers and clients or end users. Some of the connections may be between servers or clients. These connections, which may entail simply sending and receiving messages, need to be secured for practical purposes.

Individuals and organizations should protect data during online communications from cybercriminals. Thus, the need to secure online communications extends from simply protecting data during transactions to all other online activities.

There are fundamental differences in the way they function; however, they share the common feature of being protocols for securing online data or communications. Let us consider the theoretical background of internet security before considering HTTPS vs. SSL in detail.

Data Encryption

The concepts of data encryption and authentication are important for understanding SSL vs. HTTPS. Data encryption helps to secure the information people send and receive online. Encryption scrambles the data so that any unauthorized person who intercepts the transfer may not read the messages. One must have a special key to decrypt the message to its meaningful form.

Security protocols like TLS and SSL facilitate data encryption and decryption. These systems provide specific procedures and rules that clients, end users, and servers can use to communicate with one another securely.

The HTTP is the standard protocol or format for transmitting data over the internet. However, this transfer protocol has one main weakness; it lacks sufficient security features to safeguard the transfer of information over the internet.

Data transfer via HTTP is open to abuse by unauthorized persons who can access it. However, the addition of SSL to the HTTP platform creates a layer of security. Under HTTPS, data encryption, decryption, and authentication take place to make it difficult for unauthorized users to access the data in its meaningful form. Thus, communication among servers and clients on the World Wide Web takes place in a secure environment, thanks to the use of the HTTPS security protocol.

SSL

What is SSL vs. HTTPS? When should you use SSL, TLS, or HTTPS? These are some of the most important questions you should consider before choosing HTTPS vs. SSL. Secure Socket Layer (SSL) is a format for protecting internet connections and the transfer of data over the internet.

The use of SSL provides a framework for encryption and authentication between connections on the World Wide Web. The system secures all types of connections: between clients, clients, and servers, and between servers. The encryption and authentication functions of SSL enable secure communication online. Unauthorized parties cannot access the contents of the communication taking place under this security protocol.

SSL was developed as a method of securing internet connections for e-commerce companies. The developers, Netscape, hoped to reduce online fraud by developing a method of securing the data and communications in the e-commerce environment from cybercriminals. However, SSL is now a standard security protocol for online activities even among individuals.

HTTPS vs. SSL

It is important to understand the issue of HTTPS vs. SSL even at the basic level. This knowledge will help you know why your browser sometimes gives you a ‘site not secure’ when you attempt to visit certain websites.

The difference between HTTPS and SSL is clear when you consider the meaning and application of HTTP. HTTP is an insecure protocol for online communication which was designed as a standard format for the transfer of information online across connections.

Under HTTP, websites send requests to servers for information they need to load pages. Every request from a website to a server under HTTP contains the following elements: the version type, URL, HTTP method, HTTP request headers, and the body. This platform becomes secure when a layer of security, SSL, is added to it. Thus, HTTP becomes HTTPS when a layer of SSL is added to the HTTP framework.

Why HTTPS Matters

HTTPS matters for many reasons. First, the use of HTTPS enables users to authenticate information when they communicate online. Websites that use an SSL certificate help visitors to get additional information about them.

Visitors use the information provided by the SSL certificate to verify the authenticity of the websites when they visit them. Authentication is important for end users because it protects them from becoming victims of online impersonation. Thanks to the use of an SSL certificate in HTTPS protocol, users can easily spot criminals who may attempt to impersonate a credible website to steal data.

HTTPS is useful to website users and owners alike. The inclusion of this protocol in online communications enables website owners and users to share personal information like PINs and banking details. Furthermore, the use of this protocol helps to prevent the loss of such information to unauthorized persons online.

TLS

Transport Layer Security (TLS) is closely related to SSL. This is the reason for many people use the terms HTTPS SSL vs. TLS or simply TLS proxy when searching for information on either SSL or TLS. However, TLS is different from SSL in different ways. Similarly, a TLS proxy is different from an SSL or HTTPS proxy in terms of features, functionalities, benefits, and others.

TLS is a more advanced version of SSL. TLS is stronger than SSL in providing a secure and reliable environment for online connections and communications. This protocol, just like its version, SSL, applies to various connections, including web browsing, communications via email, and even data scraping because of its capabilities to encrypt data shared between end users or clients and servers.

TLS is better than SSL in numerous ways. For example, TLS enhances the speed of the handshake. Therefore, TLS connections take place much faster than those taking place under the SSL protocol. Furthermore, TLS has advanced cipher suites to provide more secure protection of connections than what is found in SSL. These advanced cipher suites found in the TLS protocol come with improvements in the generation and usage of encryption and description keys.

How TLS Works

The TLS security protocol works via a handshake between the client and the server. This handshake is a series of complex interactions between the two devices involved in online communication. The first of the sequence of events that take place during the TLS handshake is to identify the version of the TLS framework in use. TLS 1.3 is the current version of the framework; however, the previous versions are still effective and in use.

Identification of the specific cipher suites to be used during the connection is the next step in the handshake sequence. This event is followed by authentication of the credentials of the server by the client device. The TLS certificate is used to verify the identity of the server the client website is attempting to access.

Lastly, the cipher suite identified before generates the set of encryption keys for the handshake session. The client or user shares the encryption keys with the server during the connection.

Why TLS Matters

TLS matters because it is used to encrypt data that is shared over the internet from third parties. The need to keep data away from unauthorized access is critical for successful communication over the internet.

Also, TLS is important because it aids in authentication. Parties, including individuals and organizations, communicating online can rely on TLS to verify their authenticity. A TLS certificate helps parties to verify the identities of the others they transact or communicate with online.

More so, TLS is critical for maintaining the integrity of the data being transferred online. Recipients of the data can verify that it has not been tampered with during the transfer because of the integrity of the encryption and decryption keys system used. Only the sender and the recipient share the keys for encrypting and decrypting the data.

SSL Certificate vs. HTTPS Certificate

A practical application of SSL certificate vs. HTTPS certificate is seen in the way browsers label website addresses. Many websites nowadays have the prefix HTTPS on their domain names. This prefix denotes that the websites use SSL/TLS protocol to secure data and communications.

Many search engines nowadays label sites that do not have HTTPS as ‘not secure.’ Although the browsers do not block access to such websites, they intend to warn users to be wary of visiting them because the website owners do not use SSL/TLS as a security feature.

Furthermore, search engines reward website owners who have the HTTPS certificate installed on their sites with higher search results than those without.

How SSL Certificate vs. HTTPS Certificate Work

The strength of a TLS/SSL certificate lies in the decryption used. TLS/SSL certificates combine symmetric and asymmetric forms of cryptography to provide a highly advanced form of decryption. The difference between symmetric and asymmetric forms of cryptography is simple. Whereas asymmetric cryptography makes use of two sets of keys, symmetric decryption entails the generation and use of a complex 128-bit secret key between two connections.

The use of symmetric and asymmetric decryption secures communications online. The secure security keys are generated, shared between two connections, used to decrypt and decrypt the data, and then discarded. Thus, client-server communications take place in a highly secure environment when the TLS/SLL framework is employed.

Certificates

TLS/SSL certificates help to promote the reputation of businesses. Companies can purchase these certificates and install them on their web addresses. Organizations that use such certificates look more credible with secure websites than those that do not use the security certificates.

Domain Validation Certificate 

There are three types of SSL/TLS certificates for businesses. These specific types of certificates have distinct functionalities. The first one is the domain validation certificate. This is the basic form of SSL vs. HTTPS security certificate for websites. If you wish to obtain this certification for your business, you must prove that your organization owns the specific domain name.

Organization Validation Certificate 

The organization validation certificate is more advanced than the domain validation one. An organization needs to provide additional information before it gets the organizational validation certificate. For example, a company that wishes to obtain this certificate should prove that it is a duly registered organization.

Extended Validation Certificate 

The extended validation certificate, the third one in the group, is the most advanced one. This form of certification requires companies to provide proof of undertaking important steps to protect data. Thus, organizations that have this type of SSL/TLS certificate have proven their existence, control of the domain name, and existence of systems to protect customers’ data.

The organization validation and extended validation certificates are suitable for companies that directly face clients. B2C companies need such certificates to assure their visitors of their validity and commitment to protecting the data that clients provide when they visit the websites.

It is important to note that ownership of these certificates does not mean that the company’s websites are completely secure. However, the certificates provide frameworks and guidelines to help protect customers’ data during online communications.

SSL Proxy vs. HTTPS Proxy and TLS Proxy

ssl and https and tsl proxy

Any discussion on HTTPS vs. TLS vs. SSL will be incomplete without talking about SSL proxy vs. HTTPS proxy. There is nothing complicated about an SSL or TLS proxy. The use of these protocols is just one of the many ways of describing proxies.

Another method relies on the type of device that functions as the proxy. This is why we have the following types of proxies at Rayobyte: data center, mobile, and ISP. You can also categorize proxies based on the behavior of the IPs. Here, we have residential versus rotating proxies.

It is important to consider the differences in performance between simple HTTP and HTTPS or SSL proxies. These differences are in their performance, level of safety, and other attributes.

Generally, an HTTPS proxy provides high levels of data safety to users. The additional SSL layer in this type of proxy is responsible for the enhanced safety levels. This layer encrypts all the data you share with websites online. Therefore, cybercriminals cannot encrypt the data even if they manage to breach it.

The second important feature relates to anonymity. You do not want all important information about your identity and activities online to be readily available to anyone. Using an SSL proxy helps to hide your IP address and other important details about your identity.

What is an SSL or HTTPS Proxy?

Simply put, an SSL proxy is a type of proxy that utilizes the SSL security protocol. The Secure Socket Layer or SSL is the element that contributes to the Hypertext Transfer Protocol over SSL to form HTTPS.

HTTPS proxies help you to access websites or servers securely. Imagine if you would like to scrap data from a website you are interested in. If you have an SSL or HTTPS proxy, your real IP address gets concealed from the website. The HTTPS proxy encrypts the data that you share with the website during the process. Such a server is ideal for carrying out web scraping projects because it minimizes the chances of the target website blocking your IP address.

What is a TLS Proxy?

A TLS proxy or Transport Layer Security proxy helps you to communicate online securely. Although this internet security protocol started as a future of e-commerce transactions, it has developed into an industry standard. Thus, TLS proxies are now commonly used to secure communications online.

A TLS layer functions to block any connections regarded as malicious. This type of proxy also helps to prevent Distributed Denial of Service attacks. A TLS proxy accomplishes this goal by inspecting every communication between a server and a client. A brief interaction between the TLS proxy and the server helps to secure the communication and prevent any malicious attack, including DDoS.

Benefits of TLS Proxy

You can benefit from using a TLS protocol over proxy in several ways. First, a TLS proxy gives you advanced capabilities for monitoring traffic to detect any threat. Continuous monitoring of traffic is an important approach to preventing malicious activity in your network.

Second, using a TLP proxy is important for preventing DDoS. DDoS is one of the most common forms of malware attacks targeting all types of networks. A TLS proxy carries out transparent inspection processes to detect and prevent DDoS attacks.

Third, using a TLS protocol over proxy ensures maximum enforcement of all security policies for online communications. TLS proxies inspect decrypted traffic files to ensure all your data is secure during interactions with servers.

How Traffic Flows via a TLS Proxy

The purpose of an SSL or TLS proxy is to provide security for online connections between servers and clients. When a TLS proxy is used for such a connection, it acts as the ‘man-in-the-middle’ between the clients and the servers. The proxy then uses an appropriate certificate to authenticate the connection and secure the exchange of information between servers and clients.

Here is a breakdown of how an SSL or TLS proxy functions.

  • The client and server get connected via a proxy. The proxy connects to the server on the one hand and to the client on the other to establish communication.
  • The proxy determines whether the communication between the server and the client should be decrypted. If the message should not be decrypted, the communication between the server and the client bypasses the TLS proxy.
  • If the message or connection between the server and the client should be decrypted, the proxy proceeds to decrypt it. The proxy then re-encrypts the message before sending it to its final destination.

SSL Proxy

An SSL proxy is used to protect data during movement between a server and a client. Thus, this type of server sits between the two ends of internet communications: end users and the servers. The connection between the SSL proxy and the server takes place via an unsecured HTTP protocol. However, the connection between the SSL server and the clients or end users takes place via a secure HTTPS protocol.

Benefits of using an SSL Proxy

Using an SSL proxy helps you to see any possible threats embedded in the SSL traffic. This proxy evaluates the encrypted SSL traffic between servers and clients to help you discover and deal with any threats.

More so, using an SSL proxy helps users to enforce the highest levels of security in online communications. This proxy is associated with strong security protocols to safeguard the transfer of data between end users and servers.
