## Cross-signed versions

No certificate in the CCADB has the same subject and public key as emSign Root CA - G1 with a different issuer, so a client has to carry emSign Root CA - G1 itself in its root store to trust it.


## What happens when it expires

emSign Root CA - G1 is valid until 2043-02-18, about 16.3 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 2026-11-16, Mozilla 2026-11-16.
