"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 1 intermediate CA certificates signed directly by NetLock Platina (Class Platinum) Főtanúsítvány: 1 currently valid, 0 expired and 0 revoked (revoked includes those whose parent was revoked).

Showing 1 of 1: 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

No certificate in the CCADB has the same subject and public key as NetLock Platina (Class Platinum) Főtanúsítvány with a different issuer, so a client has to carry NetLock Platina (Class Platinum) Főtanúsítvány itself in its root store to trust it.

CRL and OCSP addresses

In the root certificate

NetLock Platina (Class Platinum) Főtanúsítvány 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

NetLock Platina (Class Platinum) Főtanúsítvány is valid until 2028-12-06, about 2.1 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 NetLock Platina (Class Platinum) Főtanúsítvány by common name (NetLock Platina (Class Platinum) Főtanúsítvány) 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 The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.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: Not included)

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 "NetLock Platina (Class Platinum) Főtanúsítvány" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: EB7E05AA58E7BD328A282BF8867033F3C035342B516EE85C01673DFFFFBBFE58

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.

Linux (ca-certificates follows Mozilla: Not included)

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 "NetLock Platina (Class Platinum) Főtanúsítvány"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
  | openssl pkcs7 -print_certs -noout | grep -iF "NetLock Platina (Class Platinum) Főtanúsítvány"

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 "EB:7E:05:AA:58:E7:BD:32:8A:28:2B:F8:86:70:33:F3:C0:35:34:2B:51:6E:E8:5C:01:67:3D:FF:FF:BB:FE:58"

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 NetLock Kft. → NetLock Platina (Class Platinum) Főtanúsítvány.

Which root does my site chain to?

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