## Cross-signed versions

1 certificate(s) in the CCADB have the same subject and public key as HARICA TLS RSA Root CA 2021 but a different issuer. A server can send one of them so that clients which trust the issuing root, but not HARICA TLS RSA Root CA 2021, can still build a chain.

| Signed by | CA owner | Expires | Status | SHA-256 |
|---|---|---|---|---|
| Hellenic Academic and Research Institutions RootCA 2015 | HARICA | 2029-08-31 | Valid | 4ACD8DC6020A545A858943A553B5E0F3FC5B859AEA1746650D69CF1210F956D8 |

## What happens when it expires

HARICA TLS RSA Root CA 2021 is valid until 2045-02-13, about 18.3 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.
