What is SSL and TLS Certificate Software?

Secure sockets layer (SSL) and transport layer security (TLS) are standard methods of initiating encrypted connections between servers and clients. SSL and TLS connections are established based on SSL and TLS digital certificates. These digital certificates authenticate a website’s identity and then utilize public key infrastructure (PKI) to create links between web servers and clients. These encryption keys secure website visitor information, building digital trust by preventing cyber criminals from reading data they may attempt to steal as it's transferred from the server to the client. Unlike general encryption software, which allows users to encrypt and transmit data between two parties, SSL and TLS technologies establish connections between servers and clients by creating a TLS/SSL certificate with a unique digital signature. These certificates authenticate the domain requesting the data. If the server accepts the certificate, the data is encrypted using this client’s public key, transferred to the client, and decrypted using the client’s private key. This process is called an SSL or TLS “handshake.” There are several different types of SSL and TLS certificates which all allow for a website to utilize HTTPS encryption. Different types of certificates are suited for different purposes and require varying degrees of validation processes, which yields correspondingly secure encryption capabilities. The most secure and rigorously obtained SSL and TLS certificates are often used by large, global organizations that handle incredibly sensitive information, including healthcare organizations, financial institutions, and insurance companies. What Do SSL and TLS Stand For? SSL and TLS software, respectively, stand for secure sockets layer and transport layer security software. SSL is the predecessor to TLS, though the two terms are closely related and sometimes used interchangeably. What Types of SSL and TLS Certificates Exist? Single-domain SSL certificates: These authenticate precisely one domain and will not authenticate any other, including subdomains associated with the one domain it has been issued to authenticate. Wildcard SSL certificates: These authenticate a domain and all of its subdomains. Multi-domain SSL certificates: These authenticate multiple domains and their subdomains on the same certificate. In addition to the different types of certificates, there are three distinct levels of certificate validation, as mentioned below: Domain validation (DV) certificates: These are the least stringent to acquire and simply prove an organization controls a particular domain and are not recommended for commercial use. Organization validation (OV) certificates: The issuing CA authenticates these against a government-hosted business registry database to authenticate an organization. Extended validation (EV) certificates: The most expensive and most-vetted SSL and TLS certificate level to obtain. Leading businesses and organizations often use EV certificates to ensure digital trust in their domains.

What are the Common Features of SSL and TLS Certificate Software?

The following are some core features within SSL and TLS certificate products that can help users in multiple ways: Provide SSL and TLS certificates: A core feature of SSL and TLS certificate software is their ability for domains to present servers with certificates that authenticate their identities. SSL and TLS certificates rely on public-key cryptography, which means one or both parties knows precisely whom they are interacting with. Once the sensitive data has been transferred from the server to the client, the client’s private key is used for decryption. Implementing SSL and TLS certificates allows data requested from servers to be encrypted using HTTPS. Website visitors can ensure the page is encrypted by checking the padlock icon in the web domain bar. Delegate certificates across an entire domain: For organizations that use multiple servers, detecting when private keys have been compromised can be challenging. To mitigate this, SSL and TLS certificate software can delegate certificates across an entire domain. This means private keys are stored in a secure, more easily monitored location. Securing the certificate’s key in this manner also means there’s no need for certificate revocation if the delegated certificate used in the handshake is stolen. This is because delegated digital certificates are short lived, typically expiring after a few hours or days. This capability also means organizations do not need to expose their private keys to servers. Instead, they merely supply the delegated certificate, which the server uses to authenticate the client through code signing. Utilize trusted certificate authorities: Certificate authorities are the organizations responsible for issuing SSL and TLS certificates. They are trusted organizations that issue different types of SSL and TLS certificates based on which type the domain has requested for its particular needs. The SSL and TLS certificates that the certificate authorities issue certifies that the named domain or subject on that certificate is the owner of the associated public key. This authentication builds digital trust between servers and clients, as sensitive information and transactions are known to go to the proper parties through a secure encryption and decryption process using HTTPS.

What are the Benefits of SSL and TLS Certificates Software?

A few crucial benefits of SSL and TLS certificates software are mentioned below: Improves website security: SSL and TLS certificates improve domain security through encryption, which enables secure connections. Transferring data from servers to clients creates vulnerabilities that attackers exploit through malware and denial-of-service attacks. Without the certificate’s private key, however, even if attackers capture data during its transfer, they cannot read it. Organizations use SSL and TLS certificates to encrypt their proprietary information, including trade secrets and financial details. Other commonly encrypted information through SSL and TLS certificate implementations include employee, customer, and transaction information. Enables compliance: Though not legally required, since 2017, web browsers have strongly urged domains to acquire an SSL or TLS certificate. Through self regulation, browsers now often label websites as having an unsecured connection if they don’t have an SSL or TLS certificate and ask for the user’s consent to continue to the domain. In addition, search engines favor results from websites with SSL and TLS certificates, and domains with secure connections more frequently populate SEO-driven searches.
