Add Chunghwa Telecom CHT TrustRoot CA
This case requests inclusion of a new Chunghwa Telecom TLS Root CA, “CHT TrustRoot CA - G1,” intended to progressively replace the CA’s current hierarchy using up-to-date key material. The request includes a self-signed root certificate (RSA 4096 with SHA-256) and provides a download URL for the new root certificate, along with key generation witness and PIT/POT report links. The CA also provides links to CCADB self-assessment materials and a combined CP/CPS document for assessment. After Chrome Root Program Policy Version 1.8 took effect on 2026-02-05, the CA reissued a new intermediate CA certificate chained up to the CHT TrustRoot CA on 2026-03-12 and revoked the old intermediate on the same date. The CA stated it would submit an updated CCADB self-assessment document (Version 1.8 effective 2026-02-26) and later posted the Version 1.8 self-assessment document link. The bug remains in ASSIGNED status with no resolution recorded in the thread.
