Check whether a domain's TLS/SSL certificate is valid, trusted, and not expiring before co
Check whether a domain's TLS/SSL certificate is valid, trusted, and not expiring before connecting to it. Performs a live handshake and returns a 0–100 score and tier (VALID/WEAK/EXPIRING/EXPIRED/UNTRUSTED/INVALID) with chain trust, days-to-expiry, signature algorithm, TLS version, and cipher quality. Use before submitting credentials, posting to a webhook, or following a payment link, to catch expired, self-signed, or MITM-risk certificates.
