SSL for Free
SSL for Free provides SSL and wildcard certificates for enabling HTTPS on websites.
About SSL for Free
SSL for Free issues SSL and wildcard certificates, which are used to enable HTTPS on websites. Certificates are provided through ZeroSSL and can be created in a web app, through a REST API, or automatically through ACME. The homepage states that free certificates are issued in less than a minute and cover one or multiple domains. Free certificates are valid for 90 days, so renewal is needed, and the homepage points to ACME or Certbot for automating renewals. The homepage also says the free certificates are free for all uses, including commercial purposes. Paid Basic, Premium, and Business plans are listed with higher certificate allowances and some advanced features, along with enterprise options on request.
Certificates are only for registered domain names and cannot be issued for IP addresses. The homepage states that the private key is generated and encrypted on the user's device and can only be downloaded through the local browser while logged into the account. The homepage does not describe how the service handles other data, so this should be read as a description of key handling only.
