Information about distrusting TrustCor Systems Certification Authorities

Learn about actions that Apple is taking to distrust TrustCor Systems Certification Authorities (CA).

TrustCor Systems experienced issues related to its audits. In light of these findings, we took action to protect users in a security update.

Apple has distrusted all new certificates issued by TrustCor Systems Certification Authorities on or after December 1, 2022. For site operators using TrustCor Systems server certificates that were issued before 1 December, 2022, these certificates will remain trusted until the natural expiration of the certificate.

The following certificates are expected to be fully removed in 2024:

  1. TrustCor ECA-1 | SHA-256 Hash: 5A885DB19C01D912C5759388938CAFBBDF031AB2D48E91EE15589B42971D039C

  2. TrustCor RootCert CA-1 | SHA-256 Hash: D40E9C86CD8FE468C1776959F49EA774FA548684B6C406F3909261F4DCE2575C

  3. TrustCor RootCert CA-2 | SHA-256 Hash: 0753E940378C1BD5E3836E395DAEA5CB839E5046F1BD0EAE1951CF10FEC7C965

To avoid disruption, we encourage all website operators, system administrators, and software developers using TrustCor Systems certificates to transition to a certificate issued by an Apple-trusted CA.
