SEC_E_ENCRYPT_FAILURE
SEC_E_ENCRYPT_FAILURE signals this condition: The security package could not encrypt the requested data. The authenticated context or its cryptographic provider could not perform encryption. This can arise from invalid context state, incompatible algorithms, key access issues, or a package-specific provider failure.
What to check
- Identify the active security package and the operation that requested encryption.
- Check for earlier certificate, key, provider, or context-negotiation errors.
- Keep the negotiated protection requirements intact while investigating; lowering encryption requirements can hide a configuration defect.
