HARICA TLS RSA Root CA 2021
HARICA TLS RSA Root CA 2021 is a root CA certificate operated by HARICA (RSA 4096, valid until 2045-02-13, SHA-256 D95D0E8E). As of the latest CCADB data it is trusted for TLS server authentication by 4 of 4 major root stores: Chrome, Mozilla, Apple, Microsoft.

"Trusted for TLS" means the store includes the root with the server-authentication trust bit (Mozilla "Websites", Apple serverAuth, Microsoft Server Authentication EKU). Microsoft "NotBefore" means only certificates issued before a cutoff date are still trusted. "Constrained" means the store applies extra restrictions.

Intermediate CAs issued by this root
The CCADB lists 8 intermediate CA certificates signed directly by HARICA TLS RSA Root CA 2021: 8 currently valid, 0 expired and 0 revoked (revoked includes those whose parent was revoked).
Showing 8 of 8: valid certificates first, newest first. Each name links to its crt.sh entry by SHA-256; an arrow marks a cross-certificate for another root on this site.

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.

CRL and OCSP addresses
In the root certificate
HARICA TLS RSA Root CA 2021 itself contains no CRL Distribution Points and no OCSP (Authority Information Access) extension. That is normal for a root: clients trust it directly and do not check its own revocation status.

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.
Check whether your device trusts it
Each platform keeps its own root store. The commands below look up HARICA TLS RSA Root CA 2021 by common name (HARICA TLS RSA Root CA 2021) or fingerprint. The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.
macOS (Apple store: Included · Trusted for TLS)
Search the system roots keychain by common name. -Z prints the SHA-256 hash, which must match the fingerprint on the last line.
security find-certificate -a -c "HARICA TLS RSA Root CA 2021" -Z \
/System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: D95D0E8EDA79525BF9BEB11B14D2100D3294985F0C62D9FABD9CD999ECCB7B1DWindows (Microsoft store: Included · Trusted for TLS)
Windows identifies roots by SHA-1 thumbprint. It installs third-party roots on demand through Automatic Root Certificates Update, so "not found" can also mean the root has not been needed yet; certutil -generateSSTFromWU roots.sst downloads Microsoft's full list.
certutil -verifystore Root 022D0582FA88CE140C0679DE7F1410E945D7A56DLinux (ca-certificates follows Mozilla: Included · Trusted for TLS)
Debian, Ubuntu, Fedora and RHEL build their ca-certificates package from Mozilla's root store. Use trust list on p11-kit systems, or search the PEM bundle on Debian and Ubuntu.
# Fedora / RHEL / Arch (p11-kit)
trust list --filter=ca-anchors | grep -iF -A2 "HARICA TLS RSA Root CA 2021"

Java ships its own cacerts keystore; JDK 9 and later accept -cacerts and the default store password is changeit. Search for the SHA-256 fingerprint in colon form.
keytool -list -cacerts -storepass changeit | grep -i "D9:5D:0E:8E:DA:79:52:5B:F9:BE:B1:1B:14:D2:10:0D:32:94:98:5F:0C:62:D9:FA:BD:9C:D9:99:EC:CB:7B:1D"Android
Android's system store is maintained by Google separately from the four CCADB stores above. Open Settings → Security & privacy → More security settings → Encryption & credentials → Trusted credentials → System (menu names vary by vendor and version) and look for Hellenic Academic and Research Institutions CA → HARICA TLS RSA Root CA 2021.

List the chain your server sends and compare the last issuer with this root; the fingerprint check confirms a local copy.
