OATI: AIA CA Issuer field pointing to PEM encoded cert
Open Access Technology International, Inc. (OATI) faced a compliance issue where the Authority Information Access (AIA) CA Issuer field in their TLS certificates pointed to a PEM-encoded file instead of the required DER format. The non-compliance was identified on April 29, 2026, and remediation was completed by republishing the issuer certificate in the correct format on May 21, 2026. The incident was reported by a third party, and while the integrity of the certificate issuance was not affected, OATI acknowledged procedural gaps in their publication processes. They are now implementing improvements to prevent similar issues in the future.
- OATI published the Server Issuing CA 2025 file.
- OATI was made aware of the AIA CA Issuer pointer issue.
- OATI acknowledged the issue to the reporter.
- OATI republished the issuer certificate files in DER format.
