Let’s Encrypt
Let’s Encrypt is a free, automated CA. This platform speaks ACME to the staging directory by default and keeps production issuance behind an explicit flag.
What Let’s Encrypt provides
Domain-validated TLS certificates with a 90-day lifetime, issued through ACME. It does not issue OV or EV certificates.
How we use it
The Let’s Encrypt driver implements ACME account, order, challenge, and finalize flows. Staging is the default directory. Rate limits are respected with retries and backoff in the protocol client.
What we do not claim
We are not Let’s Encrypt. We do not sell their certificates. We automate the ACME conversation and store the resulting inventory for your organization.
