Let's Encrypt: Automated SSL Certificates

Free, automated, and open certificate authority for TLS/SSL certificates to secure websites and enable HTTPS connections

What is Let's Encrypt?

Let's Encrypt is a non-profit certificate authority that provides free TLS/SSL certificates for websites to enable HTTPS connections. It was launched in 2015 through a collaboration between the Internet Security Research Group (ISRG) and many leading technology companies and foundations.

Let's Encrypt aims to make the web more secure by providing free certificates and enabling HTTPS by default on all websites. The automated and easy certificate issuance and renewal process through the ACME protocol removes the financial and technical barriers that previously prevented many site operators from enabling HTTPS.

Some key features of Let's Encrypt include:

• Free TLS/SSL certificates issued within minutes
• Simple, automated process to obtain and renew certificates
• Short 90-day certificate lifetimes to encourage automation
• Trusted by all major browsers
• Non-profit model focused on security, privacy and access for all

Let's Encrypt has grown rapidly since its launch and as of 2022 has issued over 300 million active certificates for over 240 million websites. It hopes to secure all websites through easy-to-use encryption.
