UCA Global G2 Root

Check whether your device trusts it

Each platform keeps its own root store. The commands below look up UCA Global G2 Root by common name (UCA Global G2 Root) 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 The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.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 "UCA Global G2 Root" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: 9BEA11C976FE014764C1BE56A6F914B5A560317ABD9988393382E5161AA0493C

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 28F97816197AFF182518AA44FEC1A0CE5CB64C8A

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 "UCA Global G2 Root"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
  | openssl pkcs7 -print_certs -noout | grep -iF "UCA Global G2 Root"

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 "9B:EA:11:C9:76:FE:01:47:64:C1:BE:56:A6:F9:14:B5:A5:60:31:7A:BD:99:88:39:33:82:E5:16:1A:A0:49:3C"

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 UniTrust → UCA Global G2 Root.

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.
