US Patent 11563590 Certificate generation method

A computing resource service provider provides a certificate management service that allows customers of the computing resource service provider to create, distribute, manage, and revoke digital certificates issued by public and/or private certificate authorities. In an embodiment, when a new certificate is generated, a certificate template is used to apply various settings and policies for the new certificate. In various examples, templates may be used to establish default values, enforce required and optional values, place restrictions on one or more data fields, and enforce signature requirements. In some embodiments, the template establishes rules for rejecting certificate requests that don't conform to the template.
