ZeroSSL by ZeroSSL
Price: Free

ZeroSSL helps you to obtain SSL certificates for your website. They are issued by Let's Encrypt Certificate Authority and they are absolutely free. The renewals are also free and unlimited. Issued certificates are supported by all major browsers and operating systems.  All the keys, regardless of whether entered or generated on site, are only used by your browser to sign appropriate messages while directly communicating with Let's Encrypt API servers over an encrypted connection. The CSR (Certificate Signing Request) is also sent directly by your browser to Let's Encrypt Certificate Authority. The certificate is also downloaded by your browser directly from Let's Encrypt via an encrypted connection. None of this information is ever seen by our servers.
