announcement : library for ACME (automatically get certificates)
Posted: Sat Jan 04, 2020 11:06 am
The ACME protocol can be used to get certificates, the https://letsencrypt.org site allows you to use ACME to get free (no charge) certificates.
The library announced here implements ACME v2 (RFC 8555). An IoT device based on an ESP32 can obtain a certificate for secure communications this way.
An ACME server verifies whether the domain you request a certificate for is reachable. Many IoT devices are behind a NAT firewall which makes this hard. This library allows all that to work for multiple devices if you have one web server behind the firewall, on which the library can store a small file for a short period.
