Short reads Retries/backoff x509 vs precert Normalization

How to Download and Parse Certificate Transparency Logs at Scale

A practical overview of CT log entry retrieval, paging, and parsing. Covers why ingestion pipelines fail and what “deterministic replay” really means.

CT Log Paging: Short Reads, Retries, Backoff, and Contiguous Indices

Defensive fetch loops: rate limiting, handling partial pages, retries on 429/5xx, and why you must advance by the count actually returned.

x509 vs Precertificate Entries: What You Can Decode and How to Normalize

How leaf types differ, why precert TBSCertificate isn’t a normal x509 parse, and how to normalize fields without lying to downstream consumers.
