"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.

Cross-signed versions

1 certificate(s) in the CCADB have the same subject and public key as Hellenic Academic and Research Institutions RootCA 2015 but a different issuer. A server can send one of them so that clients which trust the issuing root, but not Hellenic Academic and Research Institutions RootCA 2015, can still build a chain.

CRL and OCSP addresses

In the root certificate

Hellenic Academic and Research Institutions RootCA 2015 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.

Addresses found in the CRL Distribution Points and OCSP fields of the 50 valid intermediates signed by Hellenic Academic and Research Institutions RootCA 2015; the number in brackets is how many of them use each address.

What happens when it expires

Hellenic Academic and Research Institutions RootCA 2015 is valid until 2040-06-30, about 13.6 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 Hellenic Academic and Research Institutions RootCA 2015 by common name (Hellenic Academic and Research Institutions RootCA 2015) 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 The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.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 "Hellenic Academic and Research Institutions RootCA 2015" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: A040929A02CE53B4ACF4F2FFC6981CE4496F755E6D45FE0B2A692BCD52523F36

Windows (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 010C0695A6981914FFBF5FC6B0B695EA29E912A6

Linux (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 "Hellenic Academic and Research Institutions RootCA 2015"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
  | openssl pkcs7 -print_certs -noout | grep -iF "Hellenic Academic and Research Institutions RootCA 2015"

Java

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 "A0:40:92:9A:02:CE:53:B4:AC:F4:F2:FF:C6:98:1C:E4:49:6F:75:5E:6D:45:FE:0B:2A:69:2B:CD:52:52:3F:36"

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 Cert. Authority → Hellenic Academic and Research Institutions RootCA 2015.
