Forge supports installing custom SSL certificates and using LetsEncrypt to generate free certificates for your websites.
LetsEncrypt provides free SSL certificates that are recognized across all major browsers.
If you need to install LetsEncrypt for multiple domains, you may separate multiple domains using commas.
Cloning a LetsEncrypt Certificate
Because of the LetsEncrypt renewal process, it is not possible to clone LetsEncrypt certificates to other sites. You should simply issue a new LetsEncrypt certificate for that site.
# Renewing LetsEncrypt Certificates
Forge will automatically renew your LetsEncrypt certificates within 21 days or less before expiration. Renewal will take place at a random day and time to avoid overwhelming the LetsEncrypt servers.
If something goes wrong while renewing a certificate, Forge will notify the server owner via email.
# Wildcard Subdomain LetsEncrypt Certificates
To install a LetsEncrypt certificate with support for wildcard subdomains, you will need to list both the wildcard subdomain and the root domain in your domain list:
*.domain.com, domain.com. LetsEncrypt only supports the
dns-01 challenge type when issuing wildcard certificates, so you will need to provide API credentials for your DNS provider.
Forge currently supports the following LetsEncrypt wildcard DNS providers:
# Cloudflare API Token
If you are using Cloudflare to manage your DNS, your Cloudflare API token must have the
Zone.DNS.Edit permissions. In addition, the token must have permissions on all zones attached to your Cloudflare account.
# Cloudflare Universal SSL Certificates
Cloudflare provides free SSL certificates to all connected domains and all their first-level subdomains. These certificates are automatically enabled on all domains and subdomains that have Cloudflare's proxy functionality enabled. However, if you have multiple nested subdomains (e.g.
staging.api.example.com), this universal certificate will not cover those domains and may cause an
ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. If your application requires multiple nested subdomains, we recommend you disable Cloudflare proxying and use a traditional SSL certificate for your Forge site.
# Route53 User Policy
If you are using Route53 to manage your DNS, your IAM user must have the
route53:ChangeResourceRecordSets permission on your domain's hosted zone. In addition, the user must have the
