DigiCert TLS RSA SHA256 2020 CA1
What is DigiCert TLS RSA SHA256 2020 CA1?
DigiCert's 2020-series RSA intermediate chaining to the legacy DigiCert Global Root CA. Used on certificates issued before the migration to the Global Root G2 hierarchy. Often confused with 'DigiCert Global G2 TLS RSA SHA256 2020 CA1' — they share a vintage and operator but chain to different DigiCert roots.

Frequently asked questions about DigiCert TLS RSA SHA256 2020 CA1
What is DigiCert TLS RSA SHA256 2020 CA1?
DigiCert TLS RSA SHA256 2020 CA1 is a publicly trusted intermediate certificate authority operated by DigiCert, 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; DigiCert TLS RSA SHA256 2020 CA1 as a CA is fine.
Is DigiCert TLS RSA SHA256 2020 CA1 a legitimate certificate authority?
Yes. DigiCert TLS RSA SHA256 2020 CA1 is a publicly trusted intermediate CA operated by DigiCert, 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; DigiCert TLS RSA SHA256 2020 CA1 keeps signing millions of legitimate sites.
Who runs the DigiCert TLS RSA SHA256 2020 CA1 certificate authority?
DigiCert TLS RSA SHA256 2020 CA1 is operated by DigiCert, Inc.. It is a RSA intermediate that chains up to the DigiCert Global Root CA root, which DigiCert, 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 DigiCert TLS RSA SHA256 2020 CA1 mean when my browser shows it as the issuer?
When a browser shows DigiCert TLS RSA SHA256 2020 CA1 as the certificate issuer for a site, it means TLS was validated through DigiCert, Inc.'s RSA chain ending at DigiCert Global Root CA. That is normal for tens of millions of legitimate sites that use DigiCert, 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 DigiCert TLS RSA SHA256 2020 CA1 show up on phishing sites?
DigiCert, 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 DigiCert TLS RSA SHA256 2020 CA1 itself.
How do I verify a certificate issued by DigiCert TLS RSA SHA256 2020 CA1?
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 DigiCert TLS RSA SHA256 2020 CA1 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 DigiCert TLS RSA SHA256 2020 CA1 and DigiCert Global G2 TLS RSA SHA256 2020 CA1?
DigiCert TLS RSA SHA256 2020 CA1 and its siblings (DigiCert Global G2 TLS RSA SHA256 2020 CA1, DigiCert TLS Hybrid ECC SHA384 2020 CA1) share the same operator (DigiCert, 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.
