5 Best Free SSL Certificate Sources

5 Best Free SSL Certificate Sources

What is SSL?

SSL (Secure Socket Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This secure link ensures that all data transferred remains private. It’s also called TLS (Transport Layer Security). Millions of websites use SSL encryption every day to secure connections and keep their customer’s data safe from monitoring and tampering

Why Use SSL?

Every website on the Internet should be served over HTTPS. Here’s why:

  • Performance: Modern SSL can actually improve page load times.
  • Search Ranking Boost: Search engines favor HTTPS websites.
  • Security: Encrypting traffic with SSL ensures nobody can snoop on your users’ data.
  • Trust: By displaying a green lock in the browser’s address bar, SSL increases visitor’s
  • Regulatory Compliance: SSL is a key component in PCI compliance


01. – Let’s Encrypt [ The Best ]

What services does Let’s Encrypt offer?

Let’s Encrypt is a global Certificate Authority (CA). We let people and organizations around the world obtain, renew, and manage SSL/TLS certificates. Our certificates can be used by websites to enable secure HTTPS connections.

Let’s Encrypt offers Domain Validation (DV) certificates. We do not offer Organization Validation (OV) or Extended Validation (EV) primarily because we cannot automate issuance for those types of certificates.

To get started using Let’s Encrypt, please visit our Getting Started page.

What does it cost to use Let’s Encrypt? Is it really free?

We do not charge a fee for our certificates. Let’s Encrypt is a nonprofit, our mission is to create a more secure and privacy-respecting Web by promoting the widespread adoption of HTTPS. Our services are free and easy to use so that every website can deploy HTTPS.

To enable HTTPS on your website, you need to get a certificate (a type of file) from a Certificate Authority (CA). Let’s Encrypt is a CA. In order to get a certificate for your website’s domain from Let’s Encrypt, you have to demonstrate control over the domain. With Let’s Encrypt, you do this using software that uses the ACME protocol, which typically runs on your web host.

To figure out what method will work best for you, you will need to know whether you have shell access (also known as SSH access) to your web host. If you manage your website entirely through a control panel like cPanel, Plesk, or WordPress, there’s a good chance you don’t have shell access. You can ask your hosting provider to be sure.

2. – Cloud Flare

Cloudflare One-Click SSL

Encrypting as much web traffic as possible to prevent data theft and other tampering is a critical step toward building a safer, better Internet. We’re proud to be the first Internet performance and security company to offer SSL protection free of charge.

Cloudflare SSL for SaaS Providers

The adoption of SSL/TLS encryption for online organizations has become a security best practice and is increasingly becoming a requirement due to pressures by large technology companies aspiring to build a safer Internet. For example, the Google Chrome web browser began visibly labeling websites not using HTTPS as “Not Secure” for their users at the end of 20161. In parallel, Mozilla’s FireFox web browser began issuing even graver warnings to users who attempt to submit information info forms not protected by HTTPS.2

3. – SSL For Free

How It Works

1. Let’s Encrypt is the first free and open CA

We generate certificates using their ACME server by using domain validation.

2. Private Keys are generated in your browser and never transmitted.

For modern browsers we generate a private key in your browser using the Web Cryptography API and the private key is never transmitted. The private key also gets deleted off your browser after the certificate is generated. If your browser does not support the Web Cryptography API then the keys will be generated on the server using the latest version of OpenSSL and outputted over SSL and never stored. For the best security you are recommended to use a supported browser for client generation. You can also provide your own CSR when using manual verification in which case the private key is handled completely on your end.

Frequently Asked Questions

1. Can I use my own CSR?

Yes, just choose one of the manual verification methods and there will be an input at the bottom before the generate certificate button to provide your own CSR.

2 Do these SSL certificates work for IP addresses?

No, certificates can only be generated for registered domain names.

3. Special Characters and Internationalized Domain Names

For domain names with special characters or international characters we automatically convert it to the Punycode representation.

4. Can Verification Files or TXT records be deleted after verification?

Yes, all verification files or records can be deleted after verification. It is used only one time for verification purposes.

4. – StartCom

StartCom offers the free Class 1 X.509 SSL certificate “StartSSL Free”, which works for web servers (SSL/TLS) as well as for E-mail encryption (S/MIME). It also offers Class 2 and 3 certificates as well as Extended Validation Certificates, where a comprehensive validation (with costs) is mandatory.

In June 2011, the company suffered a network breach which resulted in StartCom suspending issuance of digital certificates and related services for several weeks.[11] The attacker was unable to use this to issue certificates (and StartCom was the only breached provider, of six, where the attacker was blocked from doing so)

While certificates are free and unlimited for certain uses, there are limitations imposed unless an upgrade is purchased:

  • Three-year certificate validity
