\"Let'sFebruary 27, 2020, the free certification center Let’s Encrypt issued its billionth certificate.<\/a><\/noindex>.<\/p>\n

In a festive press release, project representatives recall that the previous milestone of 100 million certificates was celebrated in June 2017.<\/a><\/noindex>At that time, the share of HTTPS traffic on the internet was 58% (64% in the USA). Over the past two and a half years, these figures have significantly increased: 'Today, 81% of web pages worldwide use HTTPS, and in the United States, we are at 91%! \u2014 the team from the project is thrilled. \u2014 An incredible achievement. This is a much higher level of privacy and security for everyone.' <\/p>\n

Let’s Encrypt played a crucial role in making HTTPS certificates a utilitarian standard, and secure traffic encryption a norm on the internet.
\n<\/a><\/noindex>
\nThe beta testing of the innovative certification center Let’s Encrypt began in December 2015. A unique feature of this new center was that the certificate issuance process was initially fully automated.<\/p>\n

Automatic HTTPS setup on a server occurs in two stages. At the first stage, the agent notifies the certification center of the server administrator's rights to the domain name. For example, the verification may include creating a specific subdomain or installing an HTTP resource within the domain with a specified URI.<\/p>\n

\"Let's
\n
\nLet\u2019s Encrypt identifies the web server with the running agent by its public key. The public and private keys are generated by the agent before the first connection to the certification center. During the automatic verification, the agent performs a series of tests: for instance, it signs the received one-time password with the public key and presents an HTTP resource with a specified URI. If the digital signature is correct and all tests pass \u2014 the agent is granted rights to manage certificates for the domain.<\/p>\n

\"Let's
\n
\nAt the second stage, the agent can request, renew, and revoke certificates. The protocol used for automatic certificate issuance is a challenge-response authentication class called the Automated Certificate Management Environment (ACME). All certificate manipulations are performed without stopping the web server using the ACME client. Certbot<\/a><\/noindex>It is easy to use, works on most operating systems, and is well-documented. There is an expert mode with an expanded set of settings. Besides Certbot, there are many other ACME clients<\/a><\/noindex>. <\/p>\n

The Important Role of Let’s Encrypt<\/h1>\n

\nLet’s Encrypt has truly revolutionized the market, where commercial certification authorities previously dominated. They have almost exited the business of issuing DV certificates (Domain Validation), although they continue to sell organization validation (OV) certificates and extended validation (EV) certificates, which Let’s Encrypt does not issue as they cannot be automated. However, this is a niche product, and in the mass market, free certificates from Let’s Encrypt reign supreme.<\/p>\n

Let’s Encrypt has made automatic certificate renewal standard practice. Despite their short lifespan (90 days), the automated process eliminates the \"human factor,\" which has traditionally posed the main vulnerability in security. Domain administrators often simply forget to renew certificates, causing services to go offline. The last such incident occurred with Microsoft Teams on February 3, 2020, when the collaborative service went offline. due to an expired certificate<\/a><\/noindex>.<\/p>\n

Automatic certificate replacement via the ACME protocol prevents such incidents.<\/p>\n

While the Let’s Encrypt project serves half of the internet, in the physical world it is a small non-profit organization: \"In these two and a half years, our organization has grown, but only a little! \u2014 they write. \u2014 In June 2017, we served about 46 million websites with 11 full-time employees and an annual budget of $2.61 million. Today we serve nearly 192 million websites with 13 full-time employees and an annual budget of approximately $3.35 million. This means we are serving more than four times the number of sites with just two additional employees and a 28 percent increase in budget.\"<\/p>\n

Support for the project comes through donations<\/a><\/noindex> and sponsorship<\/a><\/noindex>.<\/p>\n

By now, HTTPS has become the de facto standard on the internet. Since last year, major browsers have been warning users about the dangers of connecting to sites that do not encrypt traffic via HTTPS. Let\u2019s Encrypt has played a significant role in this changing security landscape.<\/p>\n

Furthermore, Let\u2019s Encrypt literally revived the infrastructure of public XMPP servers<\/a><\/noindex>. Now Jabber works with reliable encryption both at the client-server and server-server levels, and the vast majority of certificates have been issued by Let\u2019s Encrypt.<\/p>\n

\"Let's
\n
\n\"As a community, we have accomplished incredible things to protect people on the internet,\" said in the press release<\/a><\/noindex>. \"Issuing one billion certificates is a testament to all the progress we've made as a community.\"
