NAVER Global Root Certification Authority

Check whether your device trusts it

Each platform keeps its own root store. The commands below look up NAVER Global Root Certification Authority by common name (NAVER Global Root Certification Authority) 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 The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.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 "NAVER Global Root Certification Authority" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: 88F438DCF8FFD1FA8F429115FFE5F82AE1E06E0C70C375FAAD717B34A49E7265

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 8F6BF2A9274ADA14A0C4F48E6127F9C01E785DD1

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 "NAVER Global Root Certification Authority"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
  | openssl pkcs7 -print_certs -noout | grep -iF "NAVER Global Root Certification Authority"

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 "88:F4:38:DC:F8:FF:D1:FA:8F:42:91:15:FF:E5:F8:2A:E1:E0:6E:0C:70:C3:75:FA:AD:71:7B:34:A4:9E:72:65"

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 NAVER BUSINESS PLATFORM Corp. → NAVER Global Root Certification Authority.

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.
