SL_REMAPPING_SP_PUB_CRYPTO_UNKNOWN_ATTRIBUTEID
What the security processor has established
Keep the symbolic result SL_REMAPPING_SP_PUB_CRYPTO_UNKNOWN_ATTRIBUTEID together with HRESULT 0xC004D208. The producer is cryptographic processing inside the security processor; at the provider, algorithm, key, hash, signature and block-processing stage used to authenticate protected licensing data, Windows determined that a cryptographic object references an attribute identifier not defined by the provider contract.
This distinction matters because this is attribute-schema mismatch, not a missing trusted-store attribute. A later “not licensed” state should not replace the first exact HRESULT in logs.
Where it sits in the licensing pipeline
Algorithm selection, key lookup, block formatting and signature verification are independent boundaries; a failure in one does not prove corruption at the others. To verify this, capture object type, attribute ID, read/write operation and API version.
Cryptographic material should be logged by identifier, length, hash or thumbprint rather than by exporting secret keys or plaintext protected data.
State to compare on both sides of the failure
- key type and key-material length
- cipher mode, block size and padding mode
- hash state and digest length
- signature format, length and verification key
- provider and algorithm identifiers
A reproducible troubleshooting path
- Use read-only inspection first: capture object type, attribute ID, read/write operation and API version.
Similar symptoms, different conditions
| Result | Different condition |
|---|---|
SL_REMAPPING_SP_PUB_CRYPTO_HASH_FINALIZED | Compared with this result, additional data was supplied after the hash object had already been finalized. |
SL_REMAPPING_SP_PUB_CRYPTO_UNKNOWN_HASHID | Compared with this result, the requested hash algorithm identifier is not recognized by the selected provider. |
SL_REMAPPING_SP_PUB_CRYPTO_KEY_NOT_AVAILABLE | Compared with it, the key identifier is known but the key cannot be used in the current protected state. |
Safe recovery direction
Query only supported attributes or update the caller and provider to compatible versions.
Representative case: A newer caller requests a key attribute from an older provider implementation.
Actions that usually destroy useful evidence
- Do not disable signature or padding validation to make the operation continue.
- Do not publish keys, decrypted license blobs or complete protected payloads in a support ticket.
