TrustAsia TLS RSA CA
What is TrustAsia TLS RSA CA?
Budget DV TLS from TrustAsia, a DigiCert partner focused on the APAC market. Commonly bundled with Chinese cloud providers (Tencent Cloud, Alibaba Cloud) and .cn hosting resellers. TrustAsia resells DigiCert-chained certificates; trust ultimately anchors at DigiCert's roots.

Frequently asked questions about TrustAsia TLS RSA CA
What is TrustAsia TLS RSA CA?
TrustAsia TLS RSA CA is a publicly trusted intermediate certificate authority operated by TrustAsia Technologies, Inc. and chained to DigiCert Global Root CA. It is recognized by all mainstream browsers and operating system trust stores, so the certificate itself is not a phishing indicator - the same intermediate signs millions of legitimate sites. phishunt only flags the specific domains listed below as suspicious; TrustAsia TLS RSA CA as a CA is fine.
Is TrustAsia TLS RSA CA a legitimate certificate authority?
Yes. TrustAsia TLS RSA CA is a publicly trusted intermediate CA operated by TrustAsia Technologies, Inc., included in the Microsoft, Apple, Google and Mozilla root trust stores. Every mainstream browser automatically accepts certificates it signs. The intermediate itself is not a phishing signal — what matters is the specific domain. phishunt flags only the suspicious domains listed below; TrustAsia TLS RSA CA keeps signing millions of legitimate sites.
Who runs the TrustAsia TLS RSA CA certificate authority?
TrustAsia TLS RSA CA is operated by TrustAsia Technologies, Inc.. It is a RSA intermediate that chains up to the DigiCert Global Root CA root, which TrustAsia Technologies, Inc. also owns. Anyone can look up the chain in the public Certificate Transparency logs; the same operator publishes a Certificate Policy / Certification Practice Statement (CP/CPS) describing how issuance and revocation work.
What does TrustAsia TLS RSA CA mean when my browser shows it as the issuer?
When a browser shows TrustAsia TLS RSA CA as the certificate issuer for a site, it means TLS was validated through TrustAsia Technologies, Inc.'s RSA chain ending at DigiCert Global Root CA. That is normal for tens of millions of legitimate sites that use TrustAsia Technologies, Inc.'s automated DV TLS. The certificate proves the connection is encrypted and that the certificate matches the hostname — it does not prove the site behind it is trustworthy. Always verify the domain name itself.
Why does TrustAsia TLS RSA CA show up on phishing sites?
TrustAsia Technologies, Inc. issues RSA domain-validated certificates automatically and at no cost (or very low cost), which is the exact workflow scammers need to put HTTPS on a throwaway domain. Domain validation only proves that the requester controls the domain name, not that the site behind it is trustworthy. phishunt lists the specific domains currently flagged below — those are the suspicious ones, not TrustAsia TLS RSA CA itself.
How do I verify a certificate issued by TrustAsia TLS RSA CA?
In a desktop browser, click the padlock in the address bar and open the certificate viewer. Confirm the issuer chain ends at DigiCert Global Root CA, that the subject matches the domain you expect, and that the notAfter date has not passed. A valid TrustAsia TLS RSA CA certificate only proves TLS was negotiated correctly — always verify the domain name itself belongs to the service you intended to visit.
What is the difference between TrustAsia TLS RSA CA and TrustAsia RSA DV TLS CA G2?
TrustAsia TLS RSA CA and its siblings (TrustAsia RSA DV TLS CA G2) share the same operator (TrustAsia Technologies, Inc.) and roll up to the same root (DigiCert Global Root CA). CAs rotate multiple intermediates so that if one key ever has to be revoked, the damage is contained. As a user, you can treat all of them as the same trust anchor.
