You often hear you need “SSL” to make your retail web page secure, you may not know what SSL actually does for your site. SSL is the acronym for Secure Sockets Layer, a protocol developed by Netscape. SSL is used to transmit private information over the Internet, and uses two keys to encrypt or code the data. You most commonly see SSL on web sites that accept credit cards. You can tell when a site is secured by SSL if the connection starts with “https” rather than “http.”
What are the Two Keys?
The two keys are the private and pubic keys needed to transmit data over the SSL protocol. When data is encrypted, the program uses one key to encrypt the data. The other key — it can work both ways — decrypts the data. If the server sends a public key to encrypt the data, the correct private key from the SSL protocol must decrypt the data. The longer the key — or the more bits in the key, the harder it is to manually decrypt the message.
What Else Does an SSL-Encrypted Message tell you?
Since the protocol creates a pair of keys for each message, only you and the person you are sending the information to has the keys. You may not personally know the person receiving the information, but you know that only that person can decrypt the message since you and the person you are sending the message to are the only two people with the keys.
How Does the Key Know Which Two People Are Sending Information?
The keys use a certificate. A root certificate, which contains information about the person you are sending information to — in this example, we will use a retailer — the retailer has a certificate on its server. The certificate has the retailer’s information, such as its name, email address, distinguished name and other information about the web site. The certificate contains the public key. When you send information to the retailer, your information is encrypted with the private key. Only the retailer with the proper public key can decrypt your information.
While there is more to the way the secure server certificate works, this is the basics of it, and you know your information is protected as long as you see the “https” in the address line. Of course, nothing is certain except death and taxes, so there is a possibility that a key could be broken, but it is unlikely, especially on a site with 256-bit encryption — remember, the longer the key, the harder it is to break.
You could use Let's encrypt for your need to encrypt.
Free SSL Certificates: One of the most significant advantages of Let's Encrypt is that it provides free SSL/TLS certificates. This allows website owners to secure their websites with encryption without incurring any financial cost.
Automated Renewal: Let's Encrypt certificates have a relatively short validity period (usually 90 days), but they offer automated renewal mechanisms. This eliminates the need for manual certificate renewal, reducing the risk of expired certificates and ensuring continuous security.
Ease of Setup: Let's Encrypt offers user-friendly tools and software clients that simplify the process of obtaining and installing SSL certificates. This accessibility makes it easier for both beginners and experienced users to secure their websites.
Wide Browser Compatibility: Certificates issued by Let's Encrypt are recognized and trusted by all major browsers. This ensures a seamless browsing experience for users, as they won't encounter security warnings when accessing websites with Let's Encrypt certificates.
Open Source and Transparency: Let's Encrypt is an open-source project, which means its code and operations are transparent. This promotes trust and allows security experts to review and audit the technology, reducing the likelihood of hidden vulnerabilities.
Disadvantages:
No insurance: One key difference between Let's Encrypt and many commercial certificate authorities is the concept of insurance or warranty offered with SSL/TLS certificates. Commercial CAs often provide insurance against financial loss in the event that the encryption provided by their certificates is compromised, leading to breaches or data loss.
Commercial CAs offer Extended Validation (EV) certificates, which come with higher insurance coverage due to the more stringent verification process involved in issuing these certificates. In case of a security incident, the CA may offer compensation to the certificate holder up to a certain amount as specified in the warranty.
Limited Validation: Let's Encrypt primarily offers Domain Validation (DV) certificates, which verify only the ownership of the domain, not the legitimacy of the entity behind the domain. This makes it susceptible to abuse by malicious actors who might use it for phishing attacks.
Short Certificate Lifespan: While automated renewal is a plus, the short validity period of Let's Encrypt certificates (90 days) can still lead to administrative overhead, especially for those managing a large number of certificates.
No Extended Validation (EV) Certificates: Let's Encrypt doesn't provide Extended Validation (EV) certificates, which offer a higher level of trust as they involve a more rigorous verification process. EV certificates display the organization's name in the browser's address bar, which can enhance user confidence.
Single Point of Failure: If Let's Encrypt were to experience technical issues or a security breach, a large number of websites relying on its certificates could be affected simultaneously, potentially causing widespread disruption.
Dependency on Automation: While automation is convenient, it can also become a disadvantage if misconfigured. Relying solely on automated tools might lead to oversight, causing certificates to lapse and compromising security.
Let's Encrypt provides a valuable service by democratizing SSL/TLS certificate provisioning and renewal. Its advantages lie in its cost-effectiveness, ease of use, and transparent approach. However, its limitations include the lack of extended validation options and the potential for misuse due to its focus on domain validation. Users should weigh these pros and cons to determine if Let's Encrypt is the right choice for their specific needs.
