Status: Rough Prototype
A collection of Rust crates useful for fetching and processing CSV data from Common CA Database (CCADB) reports. These reports offer metadata about root and intermediate certificate authorities that have been disclosed to participating root programs (e.g. Mozilla, Microsoft, and Google).
cargo fetch-included-roots
cargo fetch-all-records # May take a little while :)Offers thin wrappers around CCADB report content, preserving values unprocessed and in String form, like the raw CSV data. Consumers that wish to process this data will likely want to create newtype wrappers that further refine the data.
Utility for downloading CCADB CSV metadata reports for local processing. Hardcodes a vendored copy of the root certificate required to access CCADB such that the tool can bootstrap a root store based on the CSV content without itself needing a full root store.
Utility for best-effort mass-downloading all Mozilla included, non-revoked, issuer CRLs (full and partitioned) present in the CCADB all certificate records CSV report. This report includes issuers that chain to expired roots and CRL URLs that are broken, so some errors are to be expected. Mostly useful for building a test data corpus.
- Better handling of retries and HTTPS->HTTP protocol downgrade for CRL downloads.
Utility for converting the CCADB IncludedCACertificateReportPEMCSV.csv report into a Rust file holding the set of
Mozilla TLS trust anchors in webpki compatible format. This tool can be used to generate an updated webpki-roots
library.
This inspired a simpler solution built directly into the webpki-roots crate.
