ACME Renewal Information (ARI)

We are working on a system that will allow us to notify subscribers via API when they need to renew. This system will allow us to signal to subscribers that they need to renew prior to, for example, a revocation event.

ECDSA Root and Intermediates

We are issuing certificates from our production ECDSA intermediate to allow-listed accounts. There is no planned date for removing the allow-list.

Completed Features

Multi-Perspective Validation

We now validate domain control from multiple network perspectives.

Certificate Transparency Log

We now operate a Certificate Transparency log.

TLS ALPN Challenge Support

We’ve specified and implemented a replacement for the TLS-SNI validation method, which was discontinued for security reasons. Introducing a replacement was important for subscribers who only want to use port 443 for validation.

Wildcard Certificates

ACME v2 API

Full IPv6 Support
