"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

No certificate in the CCADB has the same subject and public key as Actalis Authentication Root CA with a different issuer, so a client has to carry Actalis Authentication Root CA itself in its root store to trust it.

CRL and OCSP addresses

In the root certificate

Actalis Authentication Root CA 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

Actalis Authentication Root CA is valid until 2030-09-22, about 3.9 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 Actalis Authentication Root CA by common name (Actalis Authentication Root CA) 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 The store status in each heading comes from the CCADB snapshot; your device can differ if it is out of date or managed by an administrator.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 "Actalis Authentication Root CA" -Z \
  /System/Library/Keychains/SystemRootCertificates.keychain | grep "SHA-256"
# SHA-256 hash: 55926084EC963A64B96E2ABE01CE0BA86A64FBFEBCC7AAB5AFC155B37FD76066

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 F373B387065A28848AF2F34ACE192BDDC78E9CAC

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

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 "55:92:60:84:EC:96:3A:64:B9:6E:2A:BE:01:CE:0B:A8:6A:64:FB:FE:BC:C7:AA:B5:AF:C1:55:B3:7F:D7:60:66"

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 Actalis S.p.A./03358520967 → Actalis Authentication Root CA.

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.
