## Cross-signed versions

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

| Signed by | CA owner | Expires | Status | SHA-256 |
|---|---|---|---|---|
| Certigna | Certigna | 2027-06-28 | Revoked | 99977BF1CA323FA96047E7DA5F93BD6CBF17010D6D8FBCE03091ECE79C857EFA |

## What happens when it expires

Certigna Root CA is valid until 2033-10-01, about 6.9 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 2026-06-14.
