How to spread Certificate Authorities like Let's Encrypt

Why

Why do we need more open certificates authorities

Differences

Alternatives to Let's Encrypt could offer a different service:

  • Be under another jurisdiction
  • Have a different policy, for example regarding Phishing and Malware (https://letsencrypt.org/2015/10/29/phishing-and-malware.html)
  • Could impose OCSP Must Staple to improve privacy and reduce costs (~152 FQDN represent 5.5B OCSP requests per day source)
  • Could provide a fallback
  • Could be open only for some tlds
  • Could have no custom rate limits
  • Could require the CAA DNS entry
  • Could require the DNSSEC/HSTS+preload/...
  • Support: could have a support in the local languages, and/or a paid one.
  • Restrict possible challenges (ex. only DNS with DNSSEC)
