  • Online validation of email address in GPG keys?
    Cacert.org provides this (http://wiki.cacert.org/PgpSigning). However, their service is not working at the moment - and regardless, would like to know if there are any other similar services that anyone is aware of. Source: over 2 years ago
  • Code signing with a non-trusted certificate
    Now, I've written a couple little modules and released them. It's not really in my budget to purchase a paid signing certificate right now, though. However, I have an account in good standing at CAcert and could get a code signing certificate. Source: about 3 years ago

  • Apple already shipped attestation on the web, and we barely noticed
    Https://zerossl.com/ is a popular alternative. https://www.buypass.com/ is another one I haven't personally tried. - Source: Hacker News / 9 months ago
  • Choosing a SSL certificate for a website
    Get a free cert from https://letsencrypt.org/, https://zerossl.com/, etc. Any modern and reasonable host will have these solutions automated and one click within their panel. Source: about 1 year ago
  • question about v6 and location...
    Letsencrypt and ZeroSSL are two certificate authorities that have an automated system for providing and renewing SSL certificates for free. We're working on some instructions for self-hosting with SSL using Docker. Source: over 1 year ago
  • Could anyone please tell me what breed of chicken this is? She’s quite large and friendly
    " has no SSL certificate, so it is not going to work for a lot the vast majority of users. You can get one for free from https://letsencrypt.org or https://zerossl.com/ or others. Most modern web browsers throw up red "UNSAFE" scare screens when they hit servers without SSL certificates. Source: over 1 year ago
  • Do I need to install SSL certificate (HTTPS) if I only use webservices in Wireguard?
    There are companies providing certs for IP address, e.g, zerossl. So it is rare but exists. Source: over 1 year ago
