mkcert is a straightforward tool that enables developers to create locally-trusted SSL certificates without complex configurations. It automatically installs a local Certificate Authority (CA) in the system trust store, allowing for secure development on local hosts. Users can generate certificates for various domains and manage their own CA with minimal effort.

The article discusses the growing concerns and chaos surrounding the management of SSL certificates, emphasizing the critical role they play in web security and the potential risks associated with improper handling. It highlights recent incidents that have led to widespread panic and the need for improved standards and practices in certificate management.

NGINX has introduced a preview release of native support for the ACME protocol through the ngx_http_acme_module, allowing users to request, install, and renew SSL/TLS certificates directly via NGINX configuration. This implementation simplifies certificate management by reducing manual errors and reliance on external tools, while enhancing security and workflow efficiency. The article outlines the ACME workflow, its benefits, and encourages users to start utilizing the new feature.

The CA/Browser Forum has voted to reduce the maximum lifespan of SSL/TLS certificates to 47 days by March 15, 2029, a significant decrease from the current 398 days. This change aims to enhance digital security by limiting the potential abuse of compromised certificates, though it is expected to increase the workload for IT administrators who must adapt to more frequent renewals.

SSL.com faced a significant security flaw in its domain validation process, allowing unauthorized issuance of TLS certificates for legitimate websites, including Alibaba Cloud's domain. A bug hunter demonstrated the exploit by obtaining certificates for domains not owned by them, prompting SSL.com to revoke 11 mis-issued certificates as a precaution. The company has temporarily disabled the flawed validation method while they work on a fix and will provide a full incident report soon.
