Letsencrypt Supports Wildcard Certificates

Let's Encrypt is a global Certificate Authority offering free SSL/TLS certificates to enable secure HTTPS connections for websites. They do not charge for their services and rely on donations and sponsorships to operate. Let's Encrypt does not provide direct support but offers documentation and community forums for assistance. In case of malicious activities on a website using their certificates, users are advised to report to Google Safe Browsing and Microsoft Smart Screen. The certificates are valid for 90 days and can be renewed automatically every 60 days. Let's Encrypt issues Domain Validation certificates and supports Subject Alternative Name (SAN) certificates but does not provide Organization Validation (OV) or Extended Validation (EV) certificates. Private keys are not stored on Let's Encrypt servers, and users can use various ACME clients like Certbot for certificate management. The organization emphasizes the importance of TLS/SSL and PKI security, providing resources for further learning.
