NTE_BAD_HASH_STATE
NTE_BAD_HASH_STATE means that the hash object is in a state in which the requested operation is not allowed. A common pattern is attempting to add more data, derive a key, or sign a hash after it has already been finalized.
Recovery steps
- Review the hash lifecycle from creation through data updates and finalization.
- Create a new hash object for a new message instead of trying to reset a finalized handle implicitly.
- Keep the order of hash, key-derivation, and signature calls explicit in diagnostics and tests.
