CRYPT_E_ATTRIBUTES_MISSING
The cryptographic message did not contain all attributes requested by the caller. This can happen when software expects optional CMS attributes to be present in every message.
What to check for CRYPT_E_ATTRIBUTES_MISSING
- Identify which attribute was requested and whether the relevant profile actually mandates it.
- Do not infer missing attributes from certificate properties; inspect the CMS signer or recipient information directly.
- Handle optional attributes explicitly instead of treating their absence as a generic certificate error.
Microsoft: CryptVerifyMessageSignature
Diagnostic interpretation
CRYPT_E_ATTRIBUTES_MISSING has the HRESULT value 0x8009100F. AllStat records the condition as “The cryptographic message does not contain all of the requested attributes.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the crypt / attributes / missing operation.
- check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
