Class swarmauri_certs_ocspverify.OcspVerifyService.OcspVerifyService

swarmauri_certs_ocspverify.OcspVerifyService.OcspVerifyService

Bases: CertServiceBase

OCSP verification service compliant with RFC 6960 and RFC 5280.

• Implements verify_cert using OCSP responders advertised in the certificate's Authority Information Access extension.
• parse_cert extracts subject/issuer, dates, and OCSP URLs.
• create_csr/create_self_signed/sign_cert are not implemented (verify-only service).
