SL_REMAPPING_SP_PUB_CRYPTO_HASH_FINALIZED
What the security processor has established
0xC004D209 maps to SL_REMAPPING_SP_PUB_CRYPTO_HASH_FINALIZED. This result belongs to cryptographic processing inside the security processor and narrows the operation to the provider, algorithm, key, hash, signature and block-processing stage used to authenticate protected licensing data. In concrete terms, additional data was supplied after the hash object had already been finalized.
For triage, this belongs to the cryptographic processing inside the security processor. The digest may be valid; the illegal action is reusing a non-reusable finalized state. Product-key changes or network tests are useful only when the evidence points back to those layers.
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, record hash-handle creation, each update, finish call and any attempted reuse flags.
Cryptographic material should be logged by identifier, length, hash or thumbprint rather than by exporting secret keys or plaintext protected data.
A reproducible troubleshooting path
- Identify the caller and operation instance that produced
0xC004D209. - Collect the code-specific evidence: record hash-handle creation, each update, finish call and any attempted reuse flags.
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
Comparison with neighboring results
| Result | Different condition |
|---|---|
SL_REMAPPING_SP_PUB_CRYPTO_KEY_NOT_AVAILABLE | Compared with this result, the key identifier is known but the key cannot be used in the current protected state. |
SL_REMAPPING_SP_PUB_CRYPTO_UNKNOWN_ATTRIBUTEID | Compared with this result, a cryptographic object references an attribute identifier not defined by the provider contract. |
SL_REMAPPING_SP_PUB_CRYPTO_KEY_NOT_FOUND | Compared with it, the selected provider has no key object for the requested identifier. |
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- Do not publish keys, decrypted license blobs or complete protected payloads in a support ticket.
What to repair—and what not to reset
Create a new hash object or explicitly use a reusable-hash capability where supported.
Representative case: A streaming verifier calls finish and then appends a final metadata block to the same handle.
