NTE_KEYSET_ENTRY_BAD

NTE_KEYSET_ENTRY_BAD means that the registered key-container entry is invalid or corrupted. The provider can find the container reference but cannot use it safely as a valid key container.

Recovery steps for NTE_KEYSET_ENTRY_BAD

  • Check whether the key material, user profile, or token-backed storage was restored or migrated incompletely.
  • Use the provider's supported repair, reenrollment, or reimport process to restore a known-good key container.
  • Back up and validate any recoverable key material before removing damaged state.

Microsoft: CryptAcquireContext

Diagnostic discriminator: Resolve the key-container registration and then open the referenced container. This status means the registered keyset entry is unusable or corrupt, not simply absent.
