The American Library Association’s Office for Intellectual Freedom announced its sponsorship of “Let’s Encrypt,†a free, automated, and open certificate authority. “Let’s Encrypt†is a service provided by the Internet Security Research Group (ISRG) and is run for the public’s benefit. It will allow anyone who owns a domain name – including libraries – to obtain a server certificate at zero cost, making it possible to encrypt data communications between servers and provide greater security for those using the internet for email, browsing, or other online tasks.
