## Cross-signed versions

1 certificate(s) in the CCADB have the same subject and public key as D-TRUST BR Root CA 1 2020 but a different issuer. A server can send one of them so that clients which trust the issuing root, but not D-TRUST BR Root CA 1 2020, can still build a chain.

| Signed by | CA owner | Expires | Status | SHA-256 |

| D-TRUST Root Class 3 CA 2 2009 | D-Trust | 2029-11-05 | Valid | 768B6746A28C48CC35024101E58F9786F56B676A3CE94C52F968EB888DD2372E |

## What happens when it expires

D-TRUST BR Root CA 1 2020 is valid until 2035-02-11, about 8.3 years after this data snapshot (2026-11-10). From that day, browsers and operating systems that check trust-anchor expiry stop accepting chains that end at this root, so any certificate that can only chain to it fails validation. Android is a known exception: it does not enforce the expiry date of trust anchors. Root programs can stop trusting it before it expires: Chrome 2027-09-14.
