Google's Go implementation of Certificate Transparency (RFC 6962), providing libraries for parsing and auditing TLS certificates, client libraries for querying CT logs, and a Trillian-backed CT log personality. It also ships CLI tools like ctclient and sctcheck for interacting with and verifying CT logs.

Use cases

• audit TLS certificates for misissuance
• query a certificate transparency log
• verify signed certificate timestamps (SCTs)
• scan an entire CT log for certificates
• run a CT log server backed by Trillian
• parse malformed X.509 certificates in Go

When to choose

• you need to interact with or audit Certificate Transparency logs in Go
• you want to operate a CT log with a Trillian backend
• you need to parse lenient/malformed X.509 certificates that strict libraries reject

When to avoid

• you need general-purpose TLS termination or a web server
• you need CT support in a language other than Go
• you just need standard strict X.509 validation - use Go's crypto/x509
