Certificate Transparency Means What, Again?

Google Chrome will begin enforcing Certificate Transparency (CT) checks within about a year; this blog post explains CT as an ecosystem of cryptographically verifiable, append-only logs that record issued certificates so misissued or fraudulent certificates can be detected. It describes how CAs, auditors, and monitoring services will submit, verify, and watch logs to spot wrongdoing (for example misissued CA-signed certificates), and advises website and service operators to learn about CT to ensure their certificates are properly logged to avoid browser access issues.
