IdenTrust Commercial Root TLS RSA CA 2

Check whether your device trusts it

Each platform keeps its own root store. The commands below look up IdenTrust Commercial Root TLS RSA CA 2 by common name (IdenTrust Commercial Root TLS RSA CA 2) 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 The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.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 "IdenTrust Commercial Root TLS RSA CA 2" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: 4C53D6746D9502530D235A82F9CF8382F5779D5DDDDBD373ABE1724FC1EFE796

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 32BCB1C3A9687BBDF2003F7FBB3BC490381C4823

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 "IdenTrust Commercial Root TLS RSA CA 2"
# Debian / Ubuntu (ca-certificates)
openssl crl2pkcs7 -nocrl -certfile /etc/ssl/certs/ca-certificates.crt \
  | openssl pkcs7 -print_certs -noout | grep -iF "IdenTrust Commercial Root TLS RSA CA 2"

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 "4C:53:D6:74:6D:95:02:53:0D:23:5A:82:F9:CF:83:82:F5:77:9D:5D:DD:DB:D3:73:AB:E1:72:4F:C1:EF:E7:96"

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 IdenTrust → IdenTrust Commercial Root TLS RSA CA 2.

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.
