## Cross-signed versions

No certificate in the CCADB has the same subject and public key as DigiCert RSA4096 Root G5 with a different issuer, so a client has to carry DigiCert RSA4096 Root G5 itself in its root store to trust it.


## What happens when it expires

DigiCert RSA4096 Root G5 is valid until 2046-01-14, about 19.2 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.
