NTE_EXISTS

NTE_EXISTS means that the application attempted to create a cryptographic object or key container that already exists. The correct action depends on whether the caller expected to open existing state or provision new state.

Correct handling for NTE_EXISTS

  • Open the existing container when the operation is intended to reuse an established key pair.
  • Use a distinct container name when the workflow requires a separate identity.
  • Do not delete or overwrite an existing key container merely to make creation succeed.
