Trust Directory
Independent public mirror of national PKI trust anchors, not an authority. Certificates are published by each national PKI (e.g., BCCR for Costa Rica); this site mirrors and structures them.

Estonia runs one of the world's most mature national eID systems. The state authority (RIA) contracts trust service providers to operate the PKI under eIDAS: SK ID Solutions AS historically, with the 2025 government root (EEGovCA2025 / ESTEID2025) now operated by Zetes Estonia OÜ. There are several roots rather than a single hierarchy, published via the Estonian ETSI Trusted List. The legacy EE Certification Centre Root CA (RSA-2048) is being retired and no longer issues new CAs, but remains a valid anchor for certificates already issued under it. First directory entry mixing RSA and EC (P-384 and P-521) roots. Phase 1 covers the national qualified anchors; roots were sourced from the SK ID Solutions repository and crt.eidpki.ee and cross-checked against SK's published SHA-1 fingerprints.
