About the issue​

Digital signatures are applied to applications, packages and documents as a cryptographically secured authenticity record. Signatures are made using digital certificates, which can either be purchased from certificate authorities or be self-issued. Certificates have a validity period during which they can be used to create signatures. Certificates can be revoked by the certificate authority that issued them. While there can be multiple reasons for revocation, users are advised against using software applications signed with revoked certificates. This warning indicates the signing certificate was revoked before the signature had been made. Releasing software components signed with revoked certificates may result in application errors and availability outages.

How to resolve the issue​

  • Acquire a new certificate and re-sign the software component, then publish the software package again.
